For testing I am multiplying A = A * B, where A is initially identity matrix) and B is PI/2 rotation matrix. Every 4 iterations A should be back to identity, however when JIT kicks in then a11 mysteriously changes to 0 (ZERO) and remains 0, when I turn off JIT the result is just fine I got identity every 4 iterations.
I just ran this on my PC, and got a different (also wrong) result:
done in 1.247000 seconds
0 0 0 0
0 1 0 0
1 0 -1 0
0 0 0 1
I think you found a new testcase for Mike ;)
