Could you run the test under gdb and see if it is failing for any
reason that might be avoidable.  You may need to get the test
executable out of the hidden .libs/ libtool subdirectory in interp/.

(gdb) run

I can't replicate this with -g -O0 switched on. I'll have a look also with -g -O2, though my experience says this won't reveal much.
