Description
I was able to get this by recording Firefox with a lower cpu event count.
i.e. -c 5000
rr: /home/jrmuizel/src/rr/src/ReplaySession.cc:481: TrapType ReplaySession::compute_trap_type(Task*, int, SignalDeterministic, ReplaySession::ExecStateType, const ReplaySession::StepConstraints&): Assertion `DETERMINISTIC_SIG == deterministic' failed.

Research direction
Start in src/ReplaySession.cc at ReplaySession::compute_trap_type, around line 481, and reproduce the assertion while recording Firefox with a lower CPU event count such as -c 5000. Done means the reported recording and replay no longer hit the DETERMINISTIC_SIG assertion.
