Why are you checking

int(decval)


because it sure smells like int should work:

(Pdb) "3"<decval<"5"
True

That's a normal string comparison when decval is a string. This and the
ValueError is expected Python behaviour:


yes -- but i'd previously shown decval to have a length of 1, and how many things then fit that equation?

to get a meaningful traceback and post that.

I don't get a traceback -- it spews:

Fatal Python error: deletion of interned string failed

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

then crashes and I get a Microsoft pop-up that says python.exe has
encountered a problem and needs to close.

That does look bad. Most likely an extension written in C corrupts the
interpreter or it's even a bug in the interpreter itself.

I'm tight on time the rest of the day, but I think I'll next zap all the pyc versions, install a fresh 2.6.x python, and let it recompile. About the only theory I have at the moment to explain the sudden failure after years of non-failure is disk based bit-rot.
