[Mono-winforms-list] Error Running WinForms App -- Revisited

[Peter Dennis Bartok]

Freddie,

IRC channel is #mono-winforms, on irc.gimp.net.

Would love to resolve this, before we cut 1.1.13.3

Cheers,
 Peter

I started up a 'failsafe' session, which is no more than a terminal
and this is what I got:

Mono System.Windows.Forms Assembly [Revision: 54007; built: 2005/12/6

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.

I am not sure what to do now, as I get the same error every time. It
is at this point that I would fire up my Windows PC and try out the
exe, and then use 'csc' to compile the code and see what I get. So,
to check that the executable was not bad I went off and copied it to
my ubuntu computer (of which I installed what is probably an archaic
version of mono and libgdiplus) and then ran it, and for a split
second it worked (well I saw the GUI in all its 'motif' look-alike),
until I errored on me saying that I did not have a POSIX Helper DLL,
but the main point is that it is compiled correctly. As far as I can
tell the problem is with System.Windows.Forms, and if I knew the
address of your IRC channel, I would, at this point be asking a
developer to take a detailed look at my stack trace. I do run
applications like Mono-develop and a few console applications of my
own creation all the time, so the core mono runtime stuff seems to
befine.
