Do you have systemd-coredump installed?
Or differently asked: Do you know where it dumped the core on your fs?

Otherwise do this:

Please change the "set -e" at the top of /usr/lib/os-probes/50mounted-
tests after/before to "set -ex", i.e. add x.
 
And then run update-grub again.
Then it should show the exact invocation of grub-mount which segfaults

So it looks like it's one of the ntfs CVE fixes.
But I'm just guessing.

[...]

Unfortunately not or I did not issue the right command.

Please try:

# export DEBUGINFOD_URLS="https://debuginfod.debian.net"
# gdb /usr/bin/grub-mount

This is temporary directory created and used by os-prober as a mount
point. You can use any other existing directory instead.

Does grub-mount segfault only with this partition ?
AFAICS there are other NTFS partitions on your system.

Hi,

on Debian we got a bug report with a segfault in grub-mount when we
added the CVE fixes to it:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1100470

It crashes on all 3 Windows NTFS Partitions with this:

Program received signal SIGSEGV, Segmentation fault.
Download failed: Invalid argument. Continuing without source file ./obj/grub-pc/../../grub-core/fs/ntfs.c.
0x000055555557de34 in find_attr (at=at@entry=0x555555694ea0,
attr=attr@entry=128 '\200') at ../../grub-core/fs/ntfs.c:390
warning: 390 ../../grub-core/fs/ntfs.c: No such file or directory

Line 390 is the same AFAICS on upstream grub.git and Debian packaging:

while (at->attr_cur < mft_end && *at->attr_cur != 0xFF)

I don't know what is special on their NTFS partitions. I can't
reproduce this with my own dual-boot system.

You're not the only ones who have bugs reported... we're got one and Arch
as well. I sent this email to the list a week ago; I don't know where it
got lost...

Hi,

This patch also fixes an issue introduced by the original patch involving
dual booting: grub-mount seg faults when trying to mount an ntfs volume,
e.g., when grub-mkconfig is run. There are bugs for this on fedora [1] and
arch [2], so further review of this patch is really appreciated!

thanks!
marta
