BreakOnDllLoad crashes Wine

[Fabian Cenedese]

Hi

I set the registry setting BreakOnDllLoad to 1 to find a problem in the
DllMain function of my dll. Like that WineDbg stops first while loading
NTDll.dll. After continuing with c it stops again at Kernel32.dll. If I try now
to continue with c I get an "illegal instruction in 32-bit code" and I can't
continue. Without the registry setting it starts up without a problem.
Has anyone else had this problem?

(WinNT4, Wine-20020804, all dlls builtin)
