| 1 | Hi all, |
| 2 | |
| 3 | I'm trying to figure out a bug in Ethereal/Wireshark that appears only when it is compiled with a gcc profile that has SSP turned on. (For details about the bug, see http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1001 and http://bugs.gentoo.org/show_bug.cgi?id=133092) |

| 5 | After spending hours with gdb, I believe I have narrowed down the problem to a setjmp() call in the Wireshark code. That call seems to be trashing the stack, based on comparing local variable values before and after the call. Is this a known limitation of SSP, or should setjmp() work with SSP? |
