Rare bug: libcrc32c.ko causes libguestfs crash

[sickcodes]

You can fix this bug by removing whatever uses libcrc32c

For me, it was introduced here linux-apfs/linux-apfs-rw#2

You can replicate this bug via

sudo modprobe libcrc32c

And then add

    -e LIBGUESTFS_DEBUG=1 \
    -e LIBGUESTFS_TRACE=1 \
    -e MASTER_PLIST_URL='https://raw.githubusercontent.com/sickcodes/osx-serial-generator/master/config-nopicker-custom.plist' \

LIBGUESTFS output:

Not rare anymore this bug is preventing fish disk-create within the opencore-image-ng.sh script. Looking into it but don't have much time today
