If on a given platform you can tell that there isn't unwind information for the stack frame for exit, then the unwinding will stop there; it's a peculiarity of ARM unwind information that you can't tell that and need unwind information all the way up the stack until explicitly marked to stop unwinding. I don't know how or whether this (avoiding unwinding through exit) works on IA64 where everything has unwind information by default. -- http://sourceware.org/bugzilla/show_bug.cgi?id=2682 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
