See http://www.gentoo.org/proj/en/qa/backtraces.xml for info how to produce useful backtrace and reopen when ready. Thanks.
Created attachment 90645 [details] GDB Backtrace for fontforge The error is easily reproducible. Import png-image and run autotrace.
Backtrace added.
I'm also getting this error in AMD64. Here's my backtrace: #0 0x000000000053bcf7 in SplineCharFindBounds (sc=0x7fffec1280d0, bounds=0x7fffec128330) at splineutil.c:715 #1 0x00000000005630d0 in _SCAutoTrace (sc=0xb4a6c0, args=0x0) at autotrace.c:157 #2 0x0000000000563c6d in SCAutoTrace (sc=0xb4a6c0, v=0xb6be50, ask=<value optimized out>) at autotrace.c:535 #3 0x00002ae4beaec891 in gmenu_mouse (m=0xb88af0, event=0x7fffec128690) at gmenu.c:565 #4 0x00002ae4beaecdb8 in gmenu_eh (w=<value optimized out>, ge=0x7fffec128690) at gmenu.c:825 #5 0x00002ae4beb05087 in dispatchEvent (gdisp=0xa8da40, event=0x7fffec128750) at gxdraw.c:3138 #6 0x00002ae4beb069fd in GXDrawEventLoop (gd=<value optimized out>) at gxdraw.c:3237 #7 0x000000000054fc06 in FontForgeMain (argc=1, argv=0x7fffec129298) at start.c:795 #8 0x00002ae4bff96134 in __libc_start_main () from /lib/libc.so.6 #9 0x000000000041bbf9 in _start ()
you should try with the latest version, there have been autotrace fixes ...
re-open if latest fontforge doesnt address this
