Re: 4 hashes parallel on SSE2 CPUs for 0.3.6
If you haven't already, try aligning thash. It might matter. Couldn't hurt.
Looks like we're triggering a compiler bug in the tree optimizer. Can you try to compile it -O0?
No help from -O0, same error.
MinGW is GCC 3.4.5. Probably the problem.
I'll see if I can get a newer version of MinGW.
