Have you tried running under valgrind to see if it can help locate the
corruption?

ok, I have tried fontconfg cvs without my patch, but it didn''t help.
Later I found that I misspelled hinting as hint in my fonts.conf.
It''s no problem now after changing hint to hinting.:)

hi,
Today I tried fontconfig 2.4 brance, and applied my patch(see
attachment). Most of apps run fine, but gnome-terminal crashed.

Obviously memory got corrupted, but I don''t know who cause this, vte,
pango, fontconfig or my patch, I''ll try remove my patch and see what
happens tomorrow.
ps. It seems fontconfig runs faster now.
