endless loop on debugging self or nil

evaluating "self" in an inspector workspace pane

or "nil" with

"do it"

"inspect it"

works.

But if you use "debug it", enters an endless loop.

I opened a bug report for squeak (bugs.squeak.org) and

on fogbugz for pharo.

I am not sure this bug has the same cause in squeak and pharo, because

the stack trace is different.

On pharo, this behavior starts with version 50519 with integrating a fix

for issue 17251 "Quick method primitive not set correctly for #spurVMHeader"

but I don't think this is the real cause of this behavior.

Re: endless loop on debugging self or nil

Hi Nicolas,

when I select "debug it" on the expression "self" in a workspace of the code pane of an inspector, I get an information box saying "Nothign to debug; expression is optimized". Then a debugger pops up with a single frame "MethodContext >> #halt".

I am working in the Cog Spur VM r3663 in Windows 10.

No endless loop.

Best,
Marcel

No endless loop.

Yes, but only in the trunk image.

If I load the all-in-one image (image version 15113) and update to the latest version (15117), I still get this

endless loop.

Best,
Marcel
