--- Comment #5 from Andy Lutomirski <luto at kernel dot org> ---
FWIW, I just tripped over this same bug again: Xen is a bit inconsistent as to
which SS value guest user code runs with, which means that guest user code can
sometimes inadvertently run with an SS value that Linux considers unusual,
which can trigger the legacy stack switching and cause random crashes due to
this glibc bug.
