[Numpy-discussion] error compiling umathmodule.c (numpy 1.3) on 64-bit windows xp

[Lin Shao]

Hi,

I found this earlier dialog about refactoring umathmodule.c (see
bottom) where David mentioned it wasn't tested on 64-bit Windows.

I tried compiling numpy 1.3.0.dev6118 on both a 32-bit and 64-bit
Windows for Python 2.6.1 with VS 9.0, and not surprisingly, it worked
on 32-bit but not on 64-bit: the compiler returned a non-specific
"Internal Compiler Error" when working on umathmodule.c:

......

Any idea what's going on? I'd like to volunteer to test compiling
numpy on 64-bit Windows system since I have a VS 2008 professional
edition installed.

Thanks!
