I don't think this is a good idea.

I'd appreciate more details on how this could be done.  I'm no expert
on fonts nor on FreeType, and last I checked we have no one else.

Thanks.

(a) font->props[2] names the font, so:

  (gdb) pp font->props[2]

should display its name in human-readable form.  To have the "pp"
command in GDB, you need to issue the command

  (gdb) source /path/to/emacs/src/.gdbinit

before you type the above.

(b) Given your list of features, which includes XFT, I think you want
to set a breakpoint in xftfont_open, where there's a call to
XftFontOpenPattern.

Thanks.

No.  The `glyf' data of this glyph looks correct.

OK, did that.  Here's the contents of `it' ($11), `face' ($12), and
`font' ($13), respectively, at xdisp.c:28221.  The `font' entry looks
very strange.

AFAICS, it's not a problem related to a single glyph.  We rather have
to check how the `Cardo' fonts get loaded into Emacs; it looks as if
the global font descent value is incorrect.  Please tell me (a) how to
identify the font used for U+E6A3, and (b) where to set a breakpoint
to see the font loading in action.

And indeed, ttx shows the following for the global values (in the
`hhea' table):

  <ascent value="1645"/>
  <descent value="620"/>

Compare this to, say, LiberationMono-Regular:

  <ascent value="1705"/>
  <descent value="-615"/>

So we have a font error in Cardo, setting the (Apple specific) descent
with the wrong sign.

Handling the ascent and descent in OpenType is a mess, since up to
three competing sets are present in the font.  See

  http://www.typophile.com/node/13081

for a quite exhaustive discussion.

Does this explain why the descent comes out negative?  (I'm not an

The way I would suggest to put a useful breakpoint there is this:

  break x_produce_glyphs if it->char_to_display == 0xe6a3

See also a few more questions I asked in the follow-up message.

(I will try to install that font, but that might take a few days.  In
the meantime, if you can report the additional information, I might be
able to come up with a patch even without installing the font and
reproducing the problem here.)

Thanks.

No custom setup, but...

... a font that *does* have this character (following the MUFI
standard to display characters for medieval research).

  https://folk.uib.no/hnooh/mufi/

The font in question is `Cardo Regular', Version 1.045, which you
can freely download as

  http://scholarsfonts.net/cardo104.zip

(Note that the Google variant of this font doesn't contain the MUFI
characters.)

Character U+E6A3 gets mapped to glyph 3817, `uni00720325', which is
glyph `r' with a ring below; the `ttx' font disassembler shows the
following entry from the font's `glyf' table:

  <TTGlyph name="uni00720325" xMin="52" yMin="-510" xMax="747" yMax="927">
    <component glyphName="r" x="0" y="0" flags="0x204"/>
    <component glyphName="ring" x="-39" y="-1589" flags="0x4"/>
  </TTGlyph>

> and therefore Emacs displays it as "glyphless" character, showing a

Uh, oh, I'm completely lost in this function; nowhere I can get
information on the font's name.  Additionally, there is no repeatable
way to set a breakpoint right before the crash; the number of
iterations are different each time.

However, calling `strace' and searching for `open(' helped me identify
the last font that Emacs opened.

No custom setup, but...

... a font that *does* have this character (following the MUFI
standard to display characters for medieval research).

  https://folk.uib.no/hnooh/mufi/

The font in question is `Cardo Regular', Version 1.045, which you
can freely download as

  http://scholarsfonts.net/cardo104.zip

(Note that the Google variant of this font doesn't contain the MUFI
characters.)

Character U+E6A3 gets mapped to glyph 3817, `uni00720325', which is
glyph `r' with a ring below; the `ttx' font disassembler shows the
following entry from the font's `glyf' table:

  <TTGlyph name="uni00720325" xMin="52" yMin="-510" xMax="747" yMax="927">
    <component glyphName="r" x="0" y="0" flags="0x204"/>
    <component glyphName="ring" x="-39" y="-1589" flags="0x4"/>
  </TTGlyph>

Uh, oh, I'm completely lost in this function; nowhere I can get
information on the font's name.  Additionally, there is no repeatable
way to set a breakpoint right before the crash; the number of
iterations are different each time.

However, calling `strace' and searching for `open(' helped me identify
the last font that Emacs opened.

Sorry, I meant these values should be non-negatve=2E  It seems like in you=
r case, descent is -5?  How come?

Thanks=2E

Do you have some custom font setup, which is supposed to display this PUA =
character?  Because on my system, there's no font for this codepoint (as I'=
d expect), and therefore Emacs displays it as "glyphless" character, showin=
g a box with the character's code in hex, and that avoids the assertion vio=
lation=2E

So please step through x_produce_glyphs when Emacs needs to produce a glyp=
h for this character, and tell how you end up with both ascent and descent =
values zero=2E  It isn't supposed to happen with valid fonts=2E

Thanks=2E

Do you have some custom font setup, which is supposed to display this PUA =
character?  Because on my system, there's no font for this codepoint (as I'=
d expect), and therefore Emacs displays it as "glyphless" character, showin=
g a box with the character's code in hex, and that avoids the assertion vio=
lation=2E

So please step through x_produce_glyphs when Emacs needs to produce a glyp=
h for this character, and tell how you end up with both ascent and descent =
values zero=2E  It isn't supposed to happen with valid fonts=2E

Loading the attached file `bug.el' (containing the single PUA
character U+E6A3) with

  emacs -Q bug.el

causes a crash:

  xdisp.c:28955:
    Emacs fatal error:
      assertion failed:
        it->ascent >= 0 && it->descent >= 0

I've also attached the output of `bt full'.
