Yes, because ftcrfont.c is only compiled in the Cairo build, and the
problem is evidently related to it.

Yes, -ggdb should help, but I think there's something else here,
because this kind of backtrace:
#0 0x00000001012547da in FT_Done_Size ()
No symbol table info available.
#1 0x00000001002cd613 in ftcrfont_close ()

#2 0x00000001002021c5 in cleanup_vector ()
No symbol table info available.
#3 0x000000010020230a in sweep_vectors ()
No symbol table info available.
#4 0x0000000100209c63 in gc_sweep ()
No symbol table info available.
#5 0x00000001002070c0 in garbage_collect_1 ()

#6 0x0000000100207718 in Fgarbage_collect ()

#7 0x000000010016f192 in maybe_gc ()
No symbol table info available.
means there are no debugging symbols in the binary. Perhaps the
binary was stripped at link time, or when you installed it?
