Comment(by pv):

 The crash is most likely due to the improved test coverage, and it
 probably is not a programming error per se, as Valgrind on Linux x86_64
 shows nothing of concern.

 Can you try running the tests in `scipy.sparse.linalg.isolve` separately
 as the crash can also come from there?

 The traceback is not very useful. Can you run it under Valgrind (with
 Python supressions  http://projects.scipy.org/scipy/attachment/ticket/1414
 /valgrind-python.supp)? Can you also try to recompile Scipy with
 optimizations disabled and debugging enabled, `OPT="-g3 -O0" FOPT="-g3
 -O0" python setup.py build`. Does the error appear also then?
