Fixed by the stub from a18f84c0b122a324cc050cf23a0b3d0622c7de92
Not fixed at all. (I tried that stub idea before you) cubie@Cubian:~/wine-git/build2$ ./wine ../../Downloads/Note*6.4.5/notepad++.exe fixme:actctx:parse_depend_manifests Could not find dependent assembly L"Microsoft.Windows.Common-Controls" (6.0.0.0) wine: Unhandled page fault on read access to 0x30435454 at address 0x30435454 (thread 0037), starting debugger... [backtrace removed] cubie@Cubian:~/wine-git/build2$ ./wine --version wine-1.7.44-42-gb75cd7e
Can you tell if that's really related to __chkstk? This bug is only about that function, not about Notepad++ not running...
It crashes very soon after the call to that function... [maybe it's the r4 not setted up properly] I will try to write an MSVC testcase soon.
that'd be awesome and a very good foundation for an implementation, thx!
Bug fixed with the help of the MSVC testcase.

Notepad and my MSVC testcase are working fine now
