if building wrk with -Oxs(the default makefile) , the value of some local variables can not be shown normally when debugging with windbg, because these variables are stored in registers, not in stacks due to -Oxs compilation option. so i decide to build wrk without -Oxs, then i must replace the -Oxs using -Oi, or compilation errors will be product due to functions: _BitScanForward, _BitScanReverse, abs. The build is totally successful. But when i use the new wrx86.exe(2.7M) instead of old wrx86.exe(2.1M), i can not login the system, the screen is gray(then will show logon dialogbox). Access violation happens. Access violation - code c0000005 (!!! second chance !!!) nt!ExpOptimizePushLockList+0x4d: 8081ab7d 8b5114 mov edx,dword ptr [ecx+14h]
