How does xcheck operator affect on stack?

How does xcheck operator affect on stack?

How does xcheck operator affect on stack?

(OP)
Hi there.

According to "Red Book", xcheck operator tests whether the operand has the executable or literal attribute. But, it seems to me xcheck operator has an influence on ps stack. I have following example:

CODE

operand exec

where operand is dynamically builded executable object.

In some cases, operand execution causes to stack crashing, but if I will use xcheck before exec, means

CODE

operand xcheck pop exec

operand execution will finish good.

My question is:
Do you know something about xcheck influence, or similiar behavior is my particular case?

Thank you,
Michael
