Package: libgcc-s1
Version: 10-20200202-1
Severity: serious

On systems where /lib is a symlink to /usr/lib (which is the case for
every new buster installation, for instance), it can easily happen that
/usr/lib/$DEB_HOST_MUTIARCH/libgcc_s.so.1 disappears on upgrades.  This
happens whenever libgcc-s1 is unpacked before the new libgcc1, because
the old libgcc1 package ships /lib/$DEB_HOST_MUTIARCH/libgcc_s.so.1
which is in the same place, but unfortunately dpkg does not detect that
this means there is a file conflict.

This actually happened to me in a usrmerge chroot, here is the relevant
excerpt from dpkg.log:

Fortunately "apt reinstall libgcc-s1" remedies the situation, but if the
system is rebooted before that, the effects could be more drastic (see
#950254 and #950551).
