I agree here that MOL is still running, but still hope that Mac OS can be "continued" after the bad thing. ;)

It strange, as I said already, I'm sure I ran MacsBug under older versions of MOL and MacOS.
I'm afraid the problem is somewhat related to MacsBug or its integration with MacOS - things work fine in any other debugger such as PowerMac Debugger or CodeWarrior IDE (and they produce MAC-TRACE in the log without a crash).
What I get in the log for the test program (simultaneously with the black screen) is

I don't know whether it'll help, but that black screen seems to be in "graphic mode", that is, I can't "type" anything visible there, and it seems to keep MOL video settings.
The test program is

If you need something else, I'll be glad to do more.
