# actually killing the process that segfaulted, but if the process is run
# manually in a debugger the segfault is immediately seen as well as the
# misaligned stack access.

# There was a bad interaction between "old" 32-bit binaries on current 64-bit
# kernels with selinux enabled, where ASLR mmap would sometimes choose a low
# address and then block it for being below `vm.mmap_min_addr` -> `EACCES`.
# This is probably a kernel bug, but setting `ulimit -Hs` works around it.
# See also `src/ci/run.sh` where this takes effect.
