Lets take a example from #911.

It returns zero on exit and test suite CAN NOT detect the crash! Is it standard behavior or only works like this in this case ?

pijul init p1
cd p1
pijul add -rf /dev/urandom
# CRASH!
echo $?
0

@dblsaiko: i found a double crash, is it you? :)

[mpech@lambda p1]$ pijul add -rf /dev/urandom 
Well, this is embarrassing.

pijul had a problem and crashed. To help us diagnose the problem you can send us a crash report.

[mpech@lambda p1]$ echo $?
101

Yeah, that’s because the panic handler is installed for every thread. The inner thread panics, prints the message, then the outer thread panics because of that, and also prints the message. It looks better without the panic handler ;)

Not sure if that can be done better, I haven’t looked too closely at how the crate that prints this message (human_error) works.

Oh sorry, the crate is called human-panic.

@dblsaiko: tell me the problem only in this case or related to all panics?

I want Test suite catch all panics.

It’s only this case. If there’s other cases, they also need similar changes to make sure panics are propagated to the main thread.
