This looks like a compiler bug (gcc 3.4 is really old). einsum uses SSE intrinsics, and old gcc implementations are quite buggy in that area. Could you try the following, at line 38, to add the following: #define EINSUM_USE_SSE1 0 #define EINSUM_USE_SSE2 0 cheers, David _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
