Easy:

          cd /path/to/emacs/src
          gdb ./emacs.exe
in GDB:
          (gdb) run -Q
in Emacs:
          M-x load-file RET ../test/lisp/net/network-stream-tests.el RET
          M-x ert-run-tests-interactively RET THE-FAILING-TEST RET

where THE-FAILING-TEST is the name of the test which crashes.  Then
wait for the crash, at which point GDB will kick in.

That is possible, but I don't recommend it: by the time the unhandled
exception will be thrown which starts GDB, it's too late: the original
crash was already converted into an unhandled exception, and you will
see in GDB a backtrace that has no traces of the code which actually
crashed.
