[BUG]: static_map insert_or_apply benchmark intermittently hangs at arbitrary occupancy

Is this a duplicate?

• I confirmed there appear to be no duplicate issues for this bug (https://github.com/NVIDIA/cuCollections/issues)

Type of Bug

Silent Failure

Describe the bug

When running the static_map insert_or_apply benchmark, it either takes an excessively long time to complete or appears to deadlock.

I’m 99% confident the issue is a bug in the algorithm. The remaining 1% of doubt comes from the fact that I ran it under memcheck, racecheck, and synccheck, and none of them reported any errors: either the code hangs at runtime without triggering any failures, or it passes all checks without issue.

How to Reproduce

Running

./STATIC_MAP_BENCH -b 14 --profile -a Key=I64 -a Value=I64 --profile

can cause the benchmark to hang at any arbitrary occupancy, though sometimes it completes successfully without issues.

Expected behavior

It should not hang
