MinGW segfault on appveyor
This only happens when MinGW build in Release mode. Other compilers, Debug mode and nosetests work. Also when logged into appveyor VM, this doesn't happen
What's more strange is that only the last command in test script gives a segfault. When there are two tests (In tree testing and out of tree testing) the first test succeeds, but when the last test is removed, first test fails.
That's weird, because when AppVeyor gets to execute the first test, it can't know about the possible second test yet (or can it?).
Perhaps it was just a coincidence.
That was because the printing of the segfault in the first test was delayed due to the second test, but it was definitely in the first test. (I ran the first test with more verbosity and it failed in the first test.)
