Please use '--verbose=verbose' (or '-v v') option.  Cutter
shows test names with the options:

Yes. Cutter tries to get a backtrace with
g_on_error_stack_trace() but it may fail because some
memories may be broekn on crash...

It seems that Cutter should show crashed test name even if
a backtrace can't be gotten. I'll improve Cutter in the next
release. :)


Thanks,
