--- Comment #6 from dank at kegel dot com 2013-04-22 16:39:37 UTC --- You'd think... but I didn't find any obvious memcpy replacement. I spent some time bisecting the wine source yesterday. There appear to be at least three or four affected sites. I bisected one of the affected files with #pragma GCC optimize("-O2") ... #pragma GCC optimize("-O1") and the offending memcpy() there seems to be http://source.winehq.org/source/dlls/kernel32/process.c#L1316 There are plenty of clues to chase down, hope I have time to spend on it sometime soon.
