Package: freebirth Version: 0.3.2-7 fusebirth segfaults (at least on powerpc) when I compile it with a snapshot of GCC 4.2. I'm not entirely sure whether this is a compiler bug or one in your package, but from other cases like these it is likely that your package is doing something wrong and that newer optimizations exhibit the problem.
Maybe you or your upstream can investigate. If everything fails, I can talk to someone who knows GCC well. I've done some preliminary investigation which shows where the error is. The segfault goes away if you drop the optimization from oscillator.c. A traceback shows: Program received signal SIGSEGV, Segmentation fault. topo_sort (node=0xffff8008, order=0xfffa2968) at fuse_loops.c:43 43 for (children = node->get_children(node); (gdb) where #0 topo_sort (node=0xffff8008, order=0xfffa2968) at fuse_loops.c:43 #1 0x1000dbe8 in topo_sort (node=0x100d80d8, order=0xfffa2968) at fuse_loops.c:46 #2 0x1000dbe8 in topo_sort (node=0x100d9130, order=0xfffa2968) at fuse_loops.c:46 #3 0x1000dbe8 in topo_sort (node=0x100da9f0, order=0xfffa2968) at fuse_loops.c:46 #4 0x1000dbe8 in topo_sort (node=0x100dba88, order=0xfffa2968) at fuse_loops.c:46 #5 0x1000dbe8 in topo_sort (node=0x100ffbb8, order=0xfffa2968) at fuse_loops.c:46 #6 0x1000dc70 in fuse_loops (left=0x0, right=0x10100478, file=0x101013e8) at fuse_loops.c:119 #7 0x10006b44 in main (argc=<value optimized out>, argv=<value optimized out>) at freebirth.c:134 (gdb) > Automatic build of freebirth_0.3.2-7 on test.track.rz.uni-augsburg.de by > sbuild/powerpc 0.44 ... > gcc -g -Wall -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include > -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 > -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -O2 -c -o > oscillator.o oscillator.c ... > gcc -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm > -lpangocairo-1.0 -lfontconfig -lXext -lXrender -lXinerama -lXi -lXrandr > -lXcursor -lXfixes -lpango-1.0 -lcairo -lX11 -lgobject-2.0 -lgmodule-2.0 -ldl > -lglib-2.0 fusebirth.o oscillator.o sequencer.o envelope.o filter.o > gtkdial.o mixer.o raw_wave.o event.o sample_producer.o blender.o delay.o > reverb.o all_pass.o delay_panel.o reverb_panel.o multi_tap_delay.o > sample_freq_strip.o fuse_loops.o -lm -L/usr/lib -lgtk-x11-2.0 -o fusebirth > ./fusebirth > fused_loop.c 2>/dev/null > /bin/sh: line 1: 24295 Segmentation fault ./fusebirth >fused_loop.c > 2>/dev/null > make[1]: *** [fused_loop.c] Error 139 -- Martin Michlmayr http://www.cyrius.com/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
