[issue3697] "Fatal Python error: Cannot recover from stack overflow" on Windows buildbots

[Antoine Pitrou]

New submission from Antoine Pitrou <[EMAIL PROTECTED]>:

This error appears more or less regularly on the Windows py3k buildbots.
Today it has appeared following my changes to isinstance() /
issubclass(), but it had already appeared before, e.g.
http://www.python.org/dev/buildbot/3.0.stable/x86%20XP-4%203.0/builds/1093/step-test/0

What puzzles me is that the said "Fatal Python error" is computed in a
deterministic way (from the overflowing of the recursion counter),
therefore it shouldn't occur randomly on only some selected platforms.

It is because of the USE_STACKCHECK macro, which is only defined in
debug mode with Microsoft compilers.

Sorry, I don't know about interpreter core, and I cannot reproduce this
error. I believe Trent is more familiar with buildbot and python core
than me.
