libbacktrace is functional in GCC trunk. However, it does not yet support the Mach-O object file format. I hope to work on that at some point, but it would be great if somebody else tackled it. It's probably straightforward to implement based on code in libiberty/simple-object-mach-o.c. The libbacktrace code can be simpler than the libiberty code--compare libiberty/simple-object-elf.c and libbacktrace/elf.c. Ian
