           Summary: Segmentation Fault when attempting to run Cronos.exe
           Product: Wine
           Version: 1.3.13
          Platform: x86
        OS/Version: Solaris
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: loader
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: client902 at mail.ru


Attempting to run Cronos.exe (Russian DBMS, http://www.cronos.ru) causes
Segmentation Fault.
I discovered that the mentioned error occurs during windows libraries loading
(according their dependencies).

More precisely description (See file dlls/ntdlls/loader.c; function
find_forwarded_export()):

Finding the final function pointer for a forwarded function
OleCreateFontIndirect() in oleaut32.dll leads to loading this library in memory
followed by its initialization through calling attach_process(). But this
happens during a recursive call of fixup_imports(), i.e. before switching to an
alternative stack (in the functions call_on_stack() and switch_to_stack()).
Thus, we have a case when the DllMain() function executed on improper stack,
causing its overflow.

PS
If it happens that the unswitched stack size is large enough for normal
operation of process_attach(), then the program looks like working correctly.
