[WIP] Trying to fix the failing unit test

[soheilshahrouz]

I couldn't reproduce the unit test failure on a local machine, so I created this PR to trigger a CI run and hopefully locate the segault.

@soheilshahrouz A suggestion which might make things easier is to increase the assert level for the unit test for your test and turning on the sanitizer so you can try and catch the bug in action.

Locally you can try building with:
CMAKE_PARAMS="-DVTR_ASSERT_LEVEL=3 -DVTR_ENABLE_SANITIZE=ON"
I set the assert level to 3, but you can increase it to 4 if you really want. I think the sanitizer will be the most help. It will slow things down tremendously, but since this is a unit test it should be pretty quick.

Edit:
The CI just does not seem to be consistent; so building and running locally may be better.

My guess is that this testcase has a memory leak; and specifically how the binary is built may change when it crashes and how (which explains why it crashes in different ways each time).
