------- Comment #1 from Jonathon Jongsma (jonner)  2008-04-15 19:33 UTC -------
additional info from IRC:

(2:25:23 PM) armin: I already had problems with exceptions not getting caught
on Win32 when a dynamic library throws an exception that I tried to catch in an
executable built with a different compiler.
(2:25:28 PM) armin: Or, this is what I assumed to be the cause.
(2:25:41 PM) jonner: armin: ugh
(2:26:18 PM) jonner: so it doesn't work if the default gtkmm binaries are built
with msvc, and the application is mingw...?
(2:26:39 PM) armin: I think so

------- Comment #3 from Philip Langdale  2008-04-16 03:30 UTC -------
I did a binary search and it happened between 2.15.2 and 2.15.3. It's not
mentioned in the changelog but it's clearly there in the diff. It comes from
change 545 to optionentry.hg which introduces this definition:

#m4 _CONVERSION(`Glib::ustring',`const gchar*',`($3).empty() ? NULL :
g_strdup(($3).c_str())')

The test case seems to work for me. I get this output:

Spawning: C:\Windows\system32\cmd.exe
foo()
Error: Failed to execute child process "C:\Windows\system32\cmd.exe" (No such
file or directory)
Hello, World!


Isn't is working for you, Jonathan? Why didn't aib42 submit this bug so we
could ask him about it?
