Unfortunately you can't detect this with certainty (i.e. if $ebp points to the frame or is used for something else), that's where the problem is. In normal compiled code (libc with its load of inline asm doesn't count as that for some functions unfortunately) you can be sure that $ebp points to a frame (if not compiled with omit-frame-pointer of course). So, under the assumptions that we want this whole thing to get useful backtraces out of segfaults, and that further such segfaults in libc are not happening very often, but that they rather occur in application code (without being called back from libc code, like with qsort), it seems sensible to just rely on $ebp frames, even if it also has its share of problems. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
