Thanks. I followed the instructions, modifying .gdbinit in my home directory.
Then I did...

[nikki at router:bin]$ MONO_PATH=../lib MALLOC_CHECK_=2 gdb /opt/mono-1.1.15/bin/mono

Then I did...
(gdb) r --debug Specsoft.EPOS.ClientTestApp.exe

Then I got...

Program received signal SIG35, Real-time event 35.

What now?
