Research direction

Reproduce the failure by editing condvar_stress so RECORD_ARGS uses -c40, then inspect the assertion involving original_syscallno() and the reported gettid/munmap mismatch. Compare the behavior with issue #1182 and determine what must change so this stress case no longer triggers the assertion.

Written by the indexing model from the issue text.

Description

On my machine, if I edit condvar_stress to have -c40 in RECORD_ARGS, I get this assertion (plus "Should be entering munmap, but instead at gettid"). I'll try debugging this locally since it may be relevant to issue #1182 and fixing it will probably help debugging of #1182 at least.
