---- Reported by bill.seddon@lyquidity.com 2006-01-03 20:27:51 MST ----

I'm filing this bug because there is a request in 77073 (which is this 
report is the same as) that a Windows bug has to be reported separately. 

With 1.1.12.1 on Windows I have problems whatever I do.  1.1.9.2 works 
just fine but with the latest version I get GC errors in ASP.NET 
(reported separately) and errors with the simplest of Windows forms 
(except a form by itself with no controls on).

Since I don't know what "package" to file the report against I've 
selected an arbitrary one.

Attached are two very simple applications.  One a form with a button.  
The other a form with a button and a text box.  Whether compiled with CSC 
or MCS the executable run when using 1.1.9.2 or Windows .NET.

When run with 1.1.12.1 the simpler for will display but on exit shows:

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

When running the example, the one with a textbox (or, it seems, any other 
control) the following message is generated:

Test case for this report

The test cases includes short scripts for compiling and running the 
test forms under both 1.1.9.2 and 1.1.12.1.  The scripts set the 
path, MONO_CFG_DIR and MONO_PATH variables to the appropriate Mono 
version.  The Mono files are in the locations created by the 
installer.

Bugzilla is not retaining my selections for OS, Priority, etc.

The OS is Windows XP SP2

Since reporting this issue I have checked 1.1.10.1 and 1.1.11 as 
well.  These versions work fine.  However 1.1.12_0 remains a problem.

Both the GDI error and the RecalculateLine error have been fixed on 
12/22/05 in svn. 1.1.13 will contain the fixes.

I'm marking this one a duplicate of 76942, since the gdi error was 
not listed as a bug.

Both bugs were Windows specific.

When will there be a new build for Windows?  The motivation for 
loading the version was to contribute to the SWF testing.  While 
willing to help, I don't have the time to learn how to build the 
whole of mono under windows and have relied upon the provided builds.

It may be that this problem is addressed by a single assembly but 
I'm of dubious about a single assembly because of my other GC 
problems with 1.1.12.

Thanks
