Yes, it helps.

The value of c (4195374 = 0x40042e) doesn't make sense, I think. It's
an invalid character. Please tell what does this display:
(gdb) frame 2
(gdb) p it->string
(gdb) xstring
Also, in the same frame, what does this display:
(gdb) pgrowx it->glyph_row
For these commands to work, you need either to start GDB from the src
directory, or type "source /path/to/emacs/src/.gdbinit" from inside
GDB.
Thanks.
