Assertion `tmp_process.starttime == p->starttime' failed

[davidwagner]

Today I got the following assertion failure from cpulimit:

cpulimit: process_group.c:179: update_process_group: Assertion `tmp_process.starttime == p->starttime' failed.

It happene after the command I was running under cpulimit terminated with an error. However I don't seem to be able to reproduce it.

I'm running on Fedora 35, with cpulimit-0.2-15.20151118gitf4d2682.fc35.x86_64 installed.

Here is a backtrace:

and here is some information on the value of those two variables in frame 6:
