I am trying to install Python 2.6.2 on a 64-bit Linux machine (RedHat
Enterprise) using the Intel compiler (version 11). Even without
optimizations (-O0), I get a compilation error in the ctypes module
icc -pthread -fPIC -fno-strict-aliasing -DNDEBUG -O0 -I. -I/home/shr/

Received: complex(1.5707963267948966, 0.0)
Received value insufficiently close to expected value.
Adding optimization yields even more failed tests. My configuration
options are:
configure --prefix=$HOME CC=icc CXX=icc OPT=-O0
Did anyone encounter these problems before? Any solutions?
Thanks,
Konrad.
