Bug#887169: libc6: recent upgrade to 2.26-3 broke Steam games (Civ5)
Package: libc6
Version: 2.26-3
Severity: normal
Dear maintainers,
On a recent glibc upgrade on buster/sid (first to 2.26-2 and then
2.26-3), one Steam game (Civilization V) consistently segfaults on startup.
Similar issues have been reported in Arch Linux[1], Fedora[2], and
OpenSUSE[3], where the consensus was that building glibc with
-mstackrealign fixed the issue. (I haven't been able to get such a local
build working though)

The gdb traceback is as follows:
Thread 14 "Civ5XP" received signal SIGSEGV, Segmentation fault.
