We're using the WinSDK compilers and we're seeing the slow compilation times
here too. I've never seen the corrput .obj files, though -- it might a bug be
specific to 2005.

MSVC x64 compiler optimization algorithms appear to be inefficient. Certain
source files plus any optimization option causes it to take ages -- probably
trying to evaluate a combinatorial explosion of alternatives. 

I couldn't detect anything wrong or fancy with the source files in question. It
is not even clear why some files are slower and other not. gcc compiles the
same code, both in x86 or x64, without any sweat.

I haven't tried VS 2008 yet.
