Changelog windows/winproc.c: WINPROC_wrapper Add some padding between saved registers and the winproc arguments. Some winprocs may trash the register area.
As Mike Hearn suggested, adding some padding helped with my problem with WebPACK_42wp30_full_installer.exe. I hope, I found the right way to add that padding.
It may work for one application, but it doesn't look like a propper fix. I'd suggest there's probably something else going on that's causing stack corruption.
