In 2.4 and current cvs initsignal in signalmodule.c calls 
PyOS_getsig which calls signal with an invalid signal 
number. Under VC 7.1 (and 7.0, and probably before) 
this would return SIG_ERR however under VC 8.0 (beta) 
this causes an assertion failure.

Ew. My first thought is, is that allowed by ANSI C? I'd guess it's 
undefined behaviour. It still seems excessively unfriendly -- have you 
reported this to MS?

C99 7.14.1.1/p8 specifies
# If the request can be honored, the signal function
# returns the value of func for the most recent successful
# call to signal for the specified signal sig. Otherwise, a
# value of SIG_ERR is returned and a positive value is stored
# in errno.
So it seems to me that VC8 is in error: the request cannot
be "honored", so it should return SIG_ERR. Until/if VC8 is
released with that bug, I would like to take no action here.
When it is released, we still might consider to ignore it until
say, 8.1 comes along and fixes the bug.

See #1311784 for more discussion of this problem.

Just wanted to mention that the Visual Studio 2005 products
were officially launched on November 7th, 2005, and this
same problem occurs when compiling the Python 2.4 source
using Visual C++ 2005 Express Edition.

This is now fixed with patch #1350409.
