Z3 4.8.5 segfaults on aarch64 linux

[gebner]

While Z3 4.8.5 builds on aarch64 linux, it segfaults already on the VCs from prims.fst:

  CHECK     prims.fst
Unexpected error; please file a bug report, ideally with a minimized version of the source program that triggered the error.
Failure("Unexpexted output from Z3: no result section found:\nkilled")

This is the backtrace. (4.13.0 runs just fine for comparison.)
