[Bug 4279] New: Wine requires more stack than Windows; Doesn't allocate it.

[Wine Bugs]

           Summary: Wine requires more stack than Windows; Doesn't allocate
                    it.
           Product: Wine
           Version: 0.9.4.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-loader
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: justinmarrese(a)comcast.net


I get the following error while running the 64k Demo "Sonnet":

err:seh:setup_exception stack overflow 0 bytes in thread 0009 eip 7faa0ab3 esp
7fac1000 stack 0x7fac1000-0x7fbd0000

Changing the PE header of sonnet.exe to allocate more stack resolves the issue.
 (I used "editbin" that came with MSVC.  I can email you the modified .exe upon
request.)

This seems to indicate that Wine is using more stack space than Windows running
the same program.  I undestand That Is Not A Bug.  I do believe that Wine should
give itself more stack space when loading the PE to compensate for the difference.

In my experience, I've only tweaked stack sizes in response to seeing it
overflow.  As we cannot expect the average Windows developer to test their
program under Wine, and because Wine needs more stack than Windows, I feel it is
our responsibility to compensate.

Sonnet is available at:

With more info about Sonnet at:

Modified (working) version of Sonnet can be created by: (In an MSVC environment)
editbin /STACK:2000000 sonnet.exe
Where 2000000 is an abritrary yet sufficiently large number.

I'm running Gentoo on an Athlon (x86), updated as of last week, with Wine 0.9.4
emerged from the ~x86 branch in portage.
