Hydra Failure

Mike,

The latest Hydra failure was well captured.

  libinterp/parse-tree/oct-parse.in.yy-tst ....................terminate
called after throwing an instance of 'std::length_error'
  what():  basic_string::_S_create
panic: Aborted -- stopping myself...
attempting to save variables to 'octave-workspace'...

/tmp/nix-build-octave-0pre.drv-0/octave-4.1.0+/test

Is there any way to get an interactive session going on the Hydra VM using
this exact binary that failed?  The file oct-parse.in.yy-tst is very short
at just 70 lines, but we need to be able to play around and narrow down
which test is causing the segfault.
