Gcc isn't my usual tool chain, but I can make a guess. #2: It looks like TkpGetFontFromAttributes calls InitFont with fontPtr=0. #1: Inside InitFont, the first thing it does is check fontPtr==0, then call ckAlloc(). So now fontPtr is non-zero, which you see as the stack unwinds. It look like the real problem is in InitFont, where it calls GetFont() which is returning a zero for ftFont. When GetTkFontAttributes tries to dereference it, you get the segfault. Just like the bug report (Joe referenced) says. I don't know enough about the code to create an elegant recovery mechanism.
