I compiled Python 3.4.3 on Solaris 11, and when I ran the regression test, I get a core dump when the hash() function was being used. I went through the bug database looking for something similar but couldn't find anything.
Tests like:
test_unaligned_buffers (test.test_hash.HashEqualityTestCase) ... Fatal Python error: Bus error

I then ran the same test through gdb:
