Debugger and stepping over a function that will have a DNU

Hi,

before I try to reproduce this exactly I wondered if the following is a known issue with Pharo5. If I am in the debugger and try to step over a message send and that would generate a DNU, Pharo starts taking 99% cpu time. If I use CMD+./CTRL+. to interrupt it doesn't really work either. I get it to repaint the screen once and see a lot of message boxes with errors but the system remains unresponsive.

Is that known?

I think it is known. But there seem to be more problems in the debugger when stepping. So not easy to find the exact culprit

It was fixed here 16877 and here 19108. (last allows interrupt in such cases)

These are good candidates for back porting. I will put it on my TODO.

It was fixed only in Pharo 6. it should be mentioned in issue parameters

I added an issue to not forget:
