Public bug reported:
Steps to reproduce:
1. Run 'gs %stdin'
Expected result: Ghostscript waits to receive input on stdin
Actual result: Ghostscript segfaults
Here's the stacktrace from GDB:
Program received signal SIGSEGV, Segmentation fault.

Don't know if this is upstream bug, I haven't build a more recent version to
check.
