Small example program showing the problem
If all three "arguments" (matrix, rhs and output object) to partialPivLU are Maps, the output object is not written.
I attached you a small example program showing the problem. It is slightly more complicated than a minimal example, but this is the exact situation I would like to work.
It works fine with the devel branch. I'll investigate what goes wrong with the 3.2 branch.

Summary: Bug 890: extract_data might returns 0x0 thus breaking aliasing detection
however, we still need a more robust mechanism to detect the input/output are same in both 3.2 and devel branch.
The following changesets should be good enough to close this entry.
Summary: Add regression test for bug 890
Summary: Bug 890, add a more general routine to check that two dense object reference to the same data
