           Summary: Unhandled exception with try/catch
           Product: Wine
           Version: 4.12.1

                OS: Linux

Hello,

I  have run into a bug with try/catch blocks throwing an unhandled exception
even though I have a catch all.

I  have attached a very simple test program that when started calls a method
that just throws an exception class back to the caller.  This very simple
program works great in Windows and throws an unhandled exception in Wine and
terminates the program.

This is a critical path to my application as I have incorporated a 3rd party
library that uses exceptions for program flow rather than function return
codes. Without a fix our application becomes unstable and crashes when an
intended exception is thrown.  

I would really like a solution for the version of Wine that we are running
(4.12.1) as we have Wine running on thousands of remote computers with not easy
solution to upgrade to newer versions.  I can however deploy patches to Wine.

Thank you for any assistance with addressing this issue as I have spent the
last couple days annotating the Wine sources to try and find the root cause
without success to this point.
