Description

I got this assertion when running "rr replay" on one recording of a 64-bit Servo process:

rr: /home/mbrubeck/src/rr/rr/src/TraceStream.cc:456: bool TraceReader::read_raw_data_for_frame(const TraceFrame&, TraceReader::RawData&): Assertiontime >= frame.time()' failed`

Research direction

Start at rr/src/TraceStream.cc:456 and inspect TraceReader::read_raw_data_for_frame. Reproduce the assertion with rr replay on the reported 64-bit Servo recording, then determine the cause and verify that replay no longer aborts for the affected trace.
