* autload.cc: Avoid clobbering return address in noload on i686Corinna Vinschen2015-08-252-2/+9
| | | | | | | | | | | | | | | This fixes a long-standing problem when GetProcAddress fails to load a function. The noload code calls SetLastError on i686 without saving the edx register. Starting with Windows 7, SetLastError apparently uses $edx and the register is set to 0x00000000 on return. So the subsequent `jmp *$edx' in noload supposed to return to the caller, actually jumps to address NULL, which results in a SEGV. * autoload.cc (noload): i686 only: Save and restore $edx when calling SetLastError to avoid clobbering return address stating with Windows 7.
