Public bug reported:

I get a general protection fault when removing a lot of files from an
hfsplus partition. Most of the times a reboot solves the problem but
with one directory I now get the error all the time.

sudo rm -rf myrepos/
Segmentation fault (core dumped)

Looking at the kernel logs I find the following:
