Public bug reported:
Binary package hint: mono-devel
When I tryy to use ILGenerator.Emit the Mono runtime fails saying there
is an assertion fail in method-to-ir.c.
Here is a console extract:

Could not attach to process. If your uid matches the uid of the target

again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf

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.

dylan@ubuntu:/media/MOBEXTHDD/Code/dylannet$
1.Using Ubuntu 10.10 Maverick Meerkat
2.Using mono-devel 2.6.7-3ubuntu1
3.I expected all opcodes to be emitted without crashes(all works fine on MS
.NET)
4.The system crashed because of an assertion fail.
