[Numpy-discussion] glibc error

[Gideon Simpson]

Rerunning the tests with verbosity, it dies at:

test_single (test_linalg.TestSolve) ... ok
Ticket #652 ... *** glibc detected *** python: free(): invalid next  
size (fast): 0x0000000001e284e0 ***

I'm using ATLAS 3.8.2 and lapack 3.2.  ATLAS and lapack were all built  
with the -m64 flag.
