Bug#871229:

[Beren Minor]

Hello,

I have the same issue, with a NVME drive as well.

It looks like the segmentation fault comes from grub-probe, when
called with --target=hints_string. Attached grub-probe.log is the
output of the command that leads to a segfault.

Trying with gdb doesn't give much more information, the call stack is:

Program received signal SIGSEGV, Segmentation fault.
__strcat_sse2_unaligned () at
../sysdeps/x86_64/multiarch/strcat-sse2-unaligned.S:46
46    ../sysdeps/x86_64/multiarch/strcat-sse2-unaligned.S: No such
file or directory.
(gdb) bt
#0  __strcat_sse2_unaligned () at

../csu/libc-start.c:310
#5  0x000055555555bfea in ?? ()

I'm not sure how critical it is either but as a workaround, it's
possible to roll back to testing versions of the grub-efi-amd64-bin,
grub-efi-amd64, grub2-common packages.

Cheers,
