XSSO (http://www.opengroup.org/onlinepubs/008329799/pam_getenv.htm#tagcjh_07_08)
says, that the application has to free the return variable. Means
Solaris is right and Linux-PAM wrong according to XSSO.

But: openpam as used on *BSD and MacOS claims to be conform to XSSO,
but they also don't use a copy of the value.
Means currently Solaris is incompatible to openpam and Linux-PAM in
this regard.
