Tests give "Access violation in generated code when reading 0xffffffffffffffff"

[chenyulue]

My os is win 10, and I install hmatrix successfully. When I run hmatrix-tests by runTests 20, I get the following error messages:

------ index
+++ OK, passed 100 tests.
+++ OK, passed 100 tests.

I'm a little confused about its occurrence. It's seems related to the generated code. Anyway, some test samples succeed.

Interesting bug - the tests in hmatrix give many false positives in any event and need a good overhaul.
