Hi,
I hope this is the right place for this question:
Currently I'm working on providing a Mono plugin factory for KDE. I've
followed the instructions for embedding Mono in the wiki and it works quite
well, up to the point where I want to call mono_jit_cleanup(). It segfaults
with the following stacktrace:
**
** ERROR:(../../mono/io-layer/handles-
private.h:160):_wapi_handle_set_signal_state: assertion failed: (thr_ret == 0)

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
Aborted
I think this is connected to something the KDE/Qt internals do because if I
try a simple example without all the KDE stuff, it works well.
I'd like to fix it, but I don't really understand what the stacktrace wants to
tell me. Especially I have no clue what Especially I have no clue what
_wapi_handle_set_signal_state: assertion failed: (thr_ret == 0)
means. Could anyone explain this to me?
I could leave mono_jit_cleanup out and it would work nicely, but I guess this
creates nasty memory leaks and stuff, so I better don't.
Thanks in advance,
