Try to run the full octave test suite. Hopefully that should cover
enough cases. I tried OpenBLAS recently, compiled under MinGW
(gcc-4.6.1) [1], and although a simple test like the one above didn't
crash, more extensive testing still produced a crash.


[1]: I compiled OpenBLAS fully with gcc then dropped the DLL to
replace my existing one, then tested it with my octave compiled with
MSVC. To make sure ABI are compatible, I compiled OpenBLAS with
-mpreferred-stack-boundary=2 and -ff2c (for gfortran).
