Opening a new emacs window under X11 falls back to
"Bitstream Vera Sans" not honoring the default face I have configured.

I can change the face, but opening a new window still falls back.

When I compile the exact same source tree without '--with-nativecomp'
then the Problem vanishes.

My tree here is native-comp (a3f2373bfb604af5570c86b4ffefb23296a5bfdd)
merged with master (825b4ec338e82869dc656c7041ab2483b6c22479).

Hi Christian,

could you provide a minimal reproducer I can use to investigate?

Thanks!

I am just bisecting it and will give you reply in a moment.

For now (untested by me) you may reproduce it by

- Set the 'default' face to 'Comic Sans' or anything you never ever
  use. Either from menu-bar, editing .emacs manually or through
  customize.

- Save that.

- Confirm it got saved correctly.

- Restart Emacs.

- Still no 'Comic Sans' :(

FYI:

My system is Debian bullseye: emacs configured as following:

$ ./configure --with-nativecomp --with-cairo --enable-link-time-optimization

gives:

 rm -rf ~/.emacs.d/eln-cache/*

to have a pristine new environment



And I underestimated how long bisecting takes, will continue tomorrow.

This looks like a duplicate of 45635, which has a better recipe for
reproducing, so I'm merging the two bugs.
