I've trapped one of the spurious exceptions when starting testOOrexx,
occurring while printing the "Searching for test containers...." dots.
I'm seeing the following (the "Stack frames" are a screen copy, as I don't
know how to export it to text). Any ideas from you
more-experienced-than-me debuggers?
The offending instruction is the JMP almost at the very bottom, obviously
giving the illegal address at the top of the stack frames)
Stack frames:
[image: Inline image 1]
[image: Inline image 3]
