At the end of the test, the tracer tool is unloaded and the active
memory pools are flushed. In the flush callback, to get the activity
operation string, the RocpLoader instance is neeeded, and if the
RocpLoader is not already loaded, it attempts to dlopen the rocprofiler
library.
Calling dlopen from a global destructor hangs because the dynamic
loader lock is already owned (e.g. by dlclose).
To temporarily work around the issue, instanciate the RocpLoader when
the activities needing it are enabled.
