To overcome this, I do the following in gdb before starting target record, to work around: set __x86_64_preferred_memory_instruction=0 Following memset.S (and cacheinfo.c), this will force memset to use 'regular instruction' instead of SSE - and it allows me to reverse debug :-) Not sure this is honored in glibc 2.10 for strrchr but you could give a shoot. -- What |Removed |Added ---------------------------------------------------------------------------- CC| |pierre dot poissinger at | |gmail dot com http://sourceware.org/bugzilla/show_bug.cgi?id=10743 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
