The Ghostscript internal operator .rsdparams wasn't checking the number or

Subject: [PATCH] Bug 697846: revision to commit 4f83478c88 (.eqproc)
|
|
|
|
When using the "DELAYBIND" feature, it turns out that .eqproc can be called with
|
|
parameters that are not both procedures. In this case, it turns out, the
|
|
expectation is for the operator to return 'false', rather than throw an error.

Subject: [PATCH] Bug 697892: fix check for op stack underflow.
|
|
|
|
In the original fix, I used the wrong method to check for stack underflow, this
|
|
is using the correct method.
