Arnd has found via bisecting gcc:
7e8c2bd54af ("[AArch64] fix unsafe access to deallocated stack")
which seems to be https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63293
That seems to suggest that gcc-5.0.0 is also affected.
Looking at the changelog in Debian's gcc-8.3 packages, this doesn't
feature, so it's not easy just to look at the changelogs to work out
which versions are affected.
I checked the history to confirm that all gcc-5 releases (5.0.x is pre-release)
and later have the fix.
The gcc bugzilla mentions backports into gcc-linaro, but I do not see
them in my git history.
