Rene, I think that you confused assertion (happens only in debug build
and waits for user choice) with program crash (happens in debug and

indeed, with the limitation that my code depends on parent/child
hierachy and won't close dialogs displayed by orphaned processes. I
never noticed this to be limitation, actually - I think that crashed
process is "hanging around" when crash message is displayed by its child
process, so that "Debug" button can be used.

I agree. But this might not suppress failed assertions dialogs (in Debug).
