[pkg-lxc-devel] Bug#1023437: lxc FTBFS with glibc 2.36

[Helmut Grohne]

Source: lxc
Version: 1:5.0.1-1
Severity: serious
Tags: ftbfs
X-Debbugs-Cc: debian-glibc at lists.debian.org

lxc fails to build from source in unstable. It seems very likely that
this is due to glibc 2.36. A non-parallel build log fails as follows:
