Debugger in 7.4.1 freezing ...

This happens every single time I do this ...

We have a collection type which is very complex
(designed to live on Gemstone with caching of various kinds and
reasonably complex
       methods for accessing objects in the collection).
My problem occurs when running without Gemstone -- the collection is
equally complex
in order to be consistent with the code we run when using Gemstone.

We have "do:" which does what one would expect, but with lots of complex
code
underneath.

When I run the debugger on such an enumeration, I can walk over the do:
and that
is fine.  If I step into it, I go to the end of the block and then the
world freezes.
I have to kill the "visual.exe" task to get anything to happen.  These
is 100% repeatable.

Anyone have this kind of problem before???

Hi Dennis,

I've reported a problem with the debugger in vw7.4.1 recently. I've
attached the mail. It contains a scenario to reproduce it in a clean
image. In my case visual.exe doesn't freeze immediately, but it often
does shortly after. There appears to be a problem with how the debugger
steps through DLL/CC methods.

Alan Knight has assigned an AR to this problem.

Mark

This can happen if the code enters a critical section
that operates on DependentsFields or EventHandlers.
It can also happen if you try stepping into code that
accesses the process environment.

Basically, there are a few places that access shared
globals and stepping into this code will freeze the debugger.

Some of this has been fixed in 7.5.
