No, int8 datums are always passed by reference. If you have a
counterexample then let's see it.
Whether they *could* be passed by value on some platforms is a
different issue. One of the reasons for having macros like
DatumGetInt64 is to make such a thing transparent to source code
when/if we get around to doing it. IMHO, if your code assumes
either convention explicitly then it's broken.
A possible reading of your report is that you've failed to distinguish
int4 and int8 datums in places ... but with so few details, it's
impossible to be sure of that diagnosis.
