If you have a segmentation fault then you will need to compile 
with -g, turn on core dumps and use gdb.

$ ulimit -c unlimited
$ ./test
$ gdb ./test core

You will be provided with file and line number, well the file may 
just be a module name don't remember.

Also based on that mangled string it looks like you are running 
the Druntime unittests. I've never used the above to get at 
Unittest segfaults...
