Comment 1 Marek Safar 2012-04-24 07:46:05 UTC
This happens frequently when switching between threads
Comment 2 Marek Safar 2012-04-24 08:03:49 UTC
Created attachment 1735 [details]
test project
Comment 3 Marek Safar 2012-04-24 08:04:40 UTC
Occasionally crashes mono but mostly causes debugger to return bogus values
Comment 4 Alan McGovern 2012-05-02 10:07:59 UTC
I also frequently get this and when trying to step. Something happens and the debugger thinks it has not been suspended but the application never progresses. I haven't figured out a good repro for it
Comment 5 Jeffrey Stedfast 2012-05-03 14:54:32 UTC
Someone's going to have to create a test case I can actually use (I don't seem to have libintl.dylib so marek's test case won't run for me).

I tried creating a simple multi-threaded app but I can't reproduce this issue.
Comment 6 Jeremy Kolb 2013-06-04 16:09:54 UTC
I'm seeing this in VS 2012 on Android.  It makes it impossible to debug.
