AL test failure: AL_MayaUtilsTests (SEGFAULT)

[pmolodo]

Don't have too much more info on this one, but I get a segfault when running this test. This is the only output:

 1/77 Test #69: AL_MayaUtilsTests ...............................***Exception: SegFault  3.68 sec

This crashes in both debug and release builds. It seems to finish successfully - I see the happy green dino - but then it segfaults on python exit (with no stack trace):

[  PASSED  ] 36 tests.
               __

Stack trace:

Does anyone else see this behavior on Linux?

Also, I noticed that the return code from the test isn't used / returned:

maya-usd/plugin/al/mayautils/AL/maya/tests/mayaplugintest/CMakeLists.txt

Line 104 in a29704f

ret=maya.mel.eval('AL_maya_test_UnitTestHarness'); \

we don't need the ret= , I already have it removed locally with some other changes for the next PR. not a big deal for now.

As for Linux, I don't see this problem either in debug or release. The SegFault rings a bell and it was a case on MacOSX when we were linking statically against gtest. After we switched to linking dynamically to gtest, SegFault went away... That's all I know....

I've seen the Python crash on exit problem in our mayaUsd lib tests, and I fixed it here:

Not sure if that's what you're hitting, but if the renderSetup plugin is loaded, might be worth a try unloading it before exit.

closing this since it's a dupe of #316, and that one has a bit more details...
