----------rerun:(35/6337)*----------


Please note that the SIGSEGV crash is NOT the failure mode.
The failure mode is indicated by:

java.lang.Error: Couldn't find core file location in: ...

But the failure message doesn't make sense relative to
this message:

getCoreFileLocation found stringWithLocation = core.19215

So one part of the test claims to have found the core file
location while another part says that it couldn't find the
core file location.

The test machine in question is running macOS 10.5.3 so
that might be part of the problem.
