Segfault when using %stdin

[Edward Z. Yang]

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.
