I do have a faulting pc of 0x219a5ee4, which according to gdb is in _Unwind_GetIPInfo, but the only other frame in the backtrace is garbled. Unfortunately, when I rebuilt world I didn't think to backup libgcc_s.so.1, so that pointer might not be too helpful, since I can't get to the instruction block it's in, and the address isn't included in the core dump. If it helps at all, the CVS checkout timestamp I have is from Jul 28@21:39 EST. - Justin
