naTestCrash does not work reliably on macOS

Test with heap testing for example. Sometimes overjumps all successing tests.

Potential problem is that the desktop or download folder under macOS has a higher security setting which the user can not change. This resulted in XCode constantly asking for permission to use the Folder which, when pressing Escape, was dismissed with being "not allowed", leading to file descriptors not being able to open and hence interfering with naCrash.

Solving the issue seems to be as simple as moving all impelementations to a folder which is not one of these folders.

Tested it for a few hours and the error seems to be gone. Not a proof but within a few days time, this issue can be closed if nothing pops up anymore.
