[BUG] Jitify error on exit from gtests built with Debug

[davidwendt]

Describe the bug
The libcudf gtests which use jitify will terminate with the following error when compiled in Debug mode.

terminate called after throwing an instance of 'std::runtime_error'
  what():  Jitify fatal error:
Aborted (core dumped)

These tests all complete successfully and the error only shows after all the test have passed and the process ends.
The gtests that show this behavior

         BINARYOP_TEST
         TRANSFORM_TEST
         ROLLING_TEST
         STREAM_BINARYOP_TEST
         STREAM_TRANSFORM_TEST

Steps/Code to reproduce bug
Build libcudf with Debug and run one of the tests above. The test will complete with no errors but the terminate message appears right before the program exits.

Perhaps there is some cleanup in the jitify library that is occurring after main() completes.
