CBMC dumps core on simple example

[danielsn]

test.c is:

#include <assert.h>

void* nondet_voidp();

int main()
{
    void* p;
    *p;
}

CBMC version: CBMC version 5.12 (cbmc-5.12-156-g8911c0adb) 64-bit x86_64 macos
Operating system: OSX
Exact command line resulting in the issue: cbmc --bounds-check --div-by-zero-check --float-overflow-check --nan-check --pointer-check --pointer-overflow-check --signed-overflow-check --undefined-shift-check --unsigned-overflow-check --unwind 1 --unwinding-assertions test.c
What behaviour did you expect: CBMC not to crash
What happened instead: CBMC crashed
