Comment(by pv):
Works for me too on Linux. Didn't yet test it on Windows.
Memory fragmentation is one possible cause -- while there may be 2GB of
free memory in total, it's possible that there is no contiguous block of
the desired size available. Such failure would be more likely for large
memory blocks, so to debug this further, one should check how large the
failed memory allocation is (e.g. via a debugger breakpoint in `dexpand`
or recompiling Scipy after adding `#define DEBUG 1` on top of
scipy_slu_config.h).
