Description

I get a "Program stopped" (Suspended: Signal : 0:Signal 0) on execve calls in rr replays and a continue results in a stop loop with no progress. I was unable to find out how this stop signal is generated. A normal gdb run of the program without rr works fine.

Research direction

Start by reproducing an rr replay containing an execve call under gdb, then observe the stop and continue behavior. Trace where the suspended Signal 0 state is reported and determine what successful execution past execve should look like; done means continuing no longer enters a stop loop.
