It may be complaining about eq_destroy, because these five happen to
be all the calls to that function. Perhaps it misinterprets the
macro in luatexcoerce.h. Not that I see a reason why it should,
this function is converted by web2c just like all others. Or
perhaps it is mis-optimizing something?

Sorry, I am much more lost than you are, and I have knowledge of
nor access to the IBM compiler suite.

Best wishes,
Taco
