pamh allowed to be NULL?

[Thorsten Kukuk]

Hi,

the LSB PAM test suite expects that pamh can be NULL and the function
should not crash. With the current optimizations and usage of nonnull
attribute, it seems this is not always true anymore. I know it is
debateable if a library should crash in such cases or not and that
everybody has another opinion.

My question is: Is there any documentation which tells us how
a PAM function should behave if the pamh argument is NULL? I cannot
find this, even the LSB spec itself says nothing about this.
