Hi.
I don't have a 2.0.7 to test on at the moment. I will try again when I do.
I got rid of the object allocation inside the loop. And I retested. I
don't hit the problem with int's on the call stack. I do hit the
problem with floats and doubles.
The problem is quite easily reproducible (for me). Is someone there
with knowledge of register/stack handle able to take a look with gdb or
which ever tool you use?
Regards, Peter

Does the following code exhibit the same problem? I've modified it so it
doesn't try to allocate many foo instances within the loop.
