[New-bugs-announce] [issue12973] int_pow() implementation is incorrect

[Adam]

New submission from Adam <adam at NetBSD.org>:

int_pow() (from Objects/intobject.c) shows incorrect results when Python is compiled with Clang (llvm.org); long story short: int_pow() function should use 'unsigned long' type instead of 'long' or some code gets optimised out.

Please, refer to this bug report to find out the details:
http://llvm.org/bugs/show_bug.cgi?id=10923
