Bug#950551: libgcc1: after libgcc1 upgrade, can't unlock luks partition at boot

[dimitris@stinpriza.org]

Package: libgcc1
Version: 1:9.2.1-25
Severity: grave
Justification: renders package unusable

hey,

after upgrading some latest packages on sid, i can no longer unlock luks
partition and boot. message:

"Please unlock disk rootfs:
libgcc_s.so.1 must be installed for pthread-cancel to work
Aborted"

so i think it's libgcc1 related.
had to chroot to disk from liveusb, downgrade some packages & finally use a
different kernel to boot.
noticed that update-initramfs with libgcc1 1:9.2.1-25 adds file : "Adding
binary /lib/x86_64-linux-gnu/libgcc_s.so.1" , while libgcc1 version
1:10-20200202-1 doesn't add any libgcc_s.so.1.

also, version from testing includes file /lib/x86_64-linux-gnu/libgcc_s.so.1,
while sid version uses /lib/libgcc_s.so.1 . libgcc-s1 also includes this file :
/usr/lib/x86_64-linux-gnu/libgcc_s.so.1

let me know if you need anymore info.

thanks,
d.
