IIRC the IA-64's architecture is significantly incompatible with pdump.
This is because function pointers are really function descriptors that
can contain a field that is not guaranteed to be constant across
invocations.
That’s an aspect of the ABI, no? And may vary on HP-UX?
XEmacs will build and even pass the unit tests but might not work
after the
machine is rebooted.
SuSe had a pretty invasive patch to fix this (by reinitialised all
function pointers in dumped data upon startup) but it's never made it
into our official releases.
