Hello,
We have managed to reproduce the issue with your binary.
Tested with (./deadlock 4 1000000):
- Raspberry Pi 1 with Raspbian Buster
- Raspberry Pi 3 with Raspbian Buster
- QEMU 4.2.0 on a Core i7-8650U Archlinux
- QEMU 4.2.0 on a Core i7-8700 Gentoo
Maybe you are using an older version of QEMU which does not have support
for Multi-Threaded TCG? One single core machines/emulation the mutex
deadlocks much less often. The occurrence depends on CPU speed and
thread numbers.
You may need to increase the thread numbers (first argument) and
iteration count (second argument) or even try to run several times.
Best regards,
Gyula FARKAS

Hello,
The segfault is from the missing command line arguments, which I did not check in sample
app. Please run it as:
$ ./deadlock 4 1000000
Does it happen with the attached binary? I couldn't reproduce in
Qemu.
best regards
Waldemar
