[Message part 1 (text/plain, inline)]

Hello.

Steps to reproduce:
1) emacs -Q
2) Open up a new .c file:
C-x C-f test.c
3) Type this text:
#define FOO        \
  /* Some comms.  */     \
  struct foobar my_foo; \
  struct foobar my_bar;

The first struct foobar after the comment is not fontified as the second
one.  That is, the second foobar has face font-lock-type-face, and
my_bar has face font-lock-variable-name-face, but the first foobar and
my_foo don't get those face values.

I actually bumped into this issue while visiting the emacs source file
src/editfns.c.  In that file, search for "#define EXTRA_CONTEXT_FIELDS"
and the problem should be evident.

I can reproduce it with the latest Emacs 26, as well as with the latest
master:

Thanks!  I can reproduce this easily, and will look into it in the next
day or two.

Of interest is the fact that if FOO is given an empty argument list
(i.e. one writes
    #define FOO()  \
    ...
), the bug doesn't happen.

Please try out the patch below.  On my system, it corrects the
fontification in both your test file and editfns.c.

Hello Alan.  Thanks for looking into this bug!

I've applied the patch and tried the recipe I provided, and it works fine.

However, when I visit editfns.c and search for EXTRA_CONTEXT_FIELDS,
like I said in my report, I see the following problem with this variables:
struct buffer *buffer_a;
struct buffer *buffer_b;
unsigned char *deletions;
unsigned char *insertions;

All but deletions have face font-lock-variable-name-face.

I can't seem to come up with a simple recipe to reproduce the problem,
so I refer you to that part of editfns.c.

All the following steps, separately with emacs -Q (or you could kill the
buffer if you want)
1) C-x C-f editfns.c
C-s extra RET
I observe deletions without its correspondent face and if I type:
SPC DEL
deletions gets font-lock-variable-name-face face.  However, if I
revert the buffer with M-x revert-buffer RET yes RET buffer_a, deletions
and the first 'buffer' lose their faces.

2) C-x C-f editfns.c
C-s deletions RET
I see that deletions has the right face.  But
M-x revert-buffer
makes it lose it (but *buffer_a keeps its face).

3) C-x C-f editfns.c
C-s extra RET
deletions without font-lock-variable-name-face.
C-l C-l
M-x revert-buffer
deletions now has font-lock-variable-name-face.

That is all the testing I could do, sorry for not being able to come up
with a better recipe.  Let me know if you see the same behavior, or what
else I could try.

Best regards,
Mauro.

Thanks, I didn't notice these last night, but I can see them now.

The problem with "deletions" seems to be triggered by the 2-line comment
in the macro not having a backslash escaping the \n.  In nearly 30 years
hacking C, I've never seen this before, and didn't even know it was
valid syntax.  However, this means at least four very commonly used
functions (c-beginning-of-macro, c-end-of-macro, c-forward-sws, and
c-backward-sws) are going to have to be amended to deal with it, and
this is inevitably going to make CC Mode slower.  :-(

I can't see at the moment any pattern with the fontification on
buffer_a.  Sometimes just scrolling the buffer a few lines makes
buffer_a lose its fontification.  But if an empty pair of parentheses is
put after EXTRA_CONTEXT_FIELDS, all these problems go away.  So they
seem related to what I half-fixed last night.

Well, that seems like quite a lot of testing to me.  :-)  Thanks for
doing it and reporting back to me so quickly.

I'll be working on the outstanding bugs here in the next few days.

I've just committed a fix to multiline comments in macros not having
escaped newlines.  This seems to solve the problem with the variable
"deletions".  That should be half the battle won.  As usual, please feel
free to test it for me.

In the end, it didn't make CC Mode more than around 0.5% slower.

I haven't yet tried combining yesterday's patch with the fix I've just
committed, but if we're lucky, the two together might solve the entire
bug.

I believe I have now fixed all these bugs, and indeed I've committed the
