Description Nic Wise 2011-12-17 11:35:41 UTC
I have a slightly oddball config.

I'm using Mono 2.10.7 (came with MD2.9), but with MD 2.8.5

If I do a quick build -> fix something -> build - fix something cycle, after 2 or 3 'rounds' (ie, about 30 seconds), the process beach balls.

I can force quit MD, and it's removed from the task manager, however the window doesn't go away, and I can't kill the mono process either. Reboot is the only option.

I assuming it's a 2.10.7 problem. Can I force 2.10.6 (or just reinstall it?). Is there any way to get a debug log out of it? Being I can't kill it (Activity Monitor or kill -9), I doubt it, but worth asking.

The unkillable process is a Mono bug, see bug 2548. You'll have to kill the matching gdb process.

The native crash that triggered it is probably GTK+.
Comment 2 Mikayla Hutchinson [MSFT] 2011-12-17 17:19:04 UTC
The workaround for the unkillable process is to set the env var MONO_DEBUG=no-gdb-backtrace but I expect you'd still get a crash. If you could attach the crash report from the Apple crash reporter that'd be useful.
Comment 3 Alan McGovern 2012-05-02 10:55:26 UTC
Newer versions of mono have fixed the issue where a native crash would cause gdb to hang, so this can be closed
Comment 4 Nic Wise 2012-05-02 11:24:10 UTC
Please close it. I've not had this problem in _ages_.
