Thats why I put the "g_free was used to deliberately crash" at the
beginning. The sample program is a test case on how mono reacts to a
glib crash. To answer your question,

The actual crash in my program happens in a third-party library on
which I have no control.

I am not asking mono recover from a crash. I am merely asking mono to
"not hang". That is an unpredicable behaviour since people want a
program to either run or not run but not stay in a middle state of
"doing nothing". Hope I am clear this time. Looking at the stack trace
I _think_ its just some bug in mono's after-crash-stacktrace-printer
which is causing the problem. Mono's behaviour (and yours too) is
absolutely right otherwise.
