           Summary: WinForms apps do not run on Mac OS X 10.6 with Mono
                    2.4.2.3
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.4.x
          Platform: x86
        OS/Version: Mac OS X 10.6
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Windows.Forms
        AssignedTo: mono-bugs at lists.ximian.com

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US;
rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3

After upgrading to Mac OS X 10.6, WinForms apps stopped working in Mono.  I
cannot verify that the 10.6 upgrade is the primary reason, but it is the only
software change between the time WinForms apps worked and when they stopped
working.

I have re-installed Mono 2.4.2.3 from the .dmg image and the problem remains. 
Building libgdiplus + Mono 2.4.2.3 from the source tarballs (with
CFLAGS="-m32") results in the same behavior but a different error message.  The
only real difference is that the Mono version built from source actually
displays the WinForms window for a second before crashing.

The same behavior is observed for all WinForms apps, from a simple example
(attached) to Red Gate's .NET Reflector (which used to work, at least on 10.5).


Output from Mono 2.4.2.3:
