Doesn't it mean that the Glenn's crash of May 1 source is
different from Simon's crash of May 21 source?

Among the differeces of src/ChangeLog shown by Simon, these
seem harmless.

And the rest are changes to xfont.c for x font-backend.
But, Glenn's crash is in the code for xft font-backend here:

#0  0xfd3c8b0c in XftLockFace () from /usr/openwin/lib/libXft.so.2
#1  0x0035acdc in xftfont_open (f=0x6794d8, entity=-2133415224, pixel_size=14)
    at xftfont.c:290

This also suggests that their crashes are the different one.

Could you please try to run Emacs as this?

% emacs --xrm 'Emacs*FontBackend: x'


% emacs --xrm 'Emacs*FontBackend: xft'
