+--TEST--
+proc_open with only one argv
+--DESCRIPTION--
+This test tries out a very esoteric functionality: Passing no argv[0] to a
+program. There's absolutely no reason anyone would do this in practice, but the
+entire point of the bypass_shell patch was to allow 100% control over the child
+process, so the option is there. Keep in mind that actually using this
+"feature" will probably crash most programs one could run, since the expression
+argc > 0 in a main() function is pretty much guaranteed by POSIX. It's
+interesting to note that PHP itself handles this case gracefully.
+--SKIPIF--
