Subject: Bug report: Reproduction of seg fault caused by musl thread creation
race condition
Hello! I recently had some C code which works normally with glibc but seg
faults sometimes with musl. I managed to reproduce the seg fault via
musl-gcc and Alpine Linux and document it here [1]. Seems to be some kind
of race condition, so hopefully you guys also get a seg fault when you
follow my reproduction steps. Hope this helps and looking forward to any
feedback or helping further if possible, Simon
P.S. musl newbie question: Why does my binary built on Alpine Linux report
a .so being loaded by ldd, but on Ubuntu the same binary is reported as
being static? Also, detail that here [1] too.
