Comment(by doughera):
I don't understand this ticket at all. What is this hypothetical "--
64compat" ?
I do see this puzzling note in auto/alignptrs.pm:
# On 8-byte ptr_alignment we cannot read 4-byte pbc's. Warn the user
about it.
But surely this is just a limitation of the current pbc reader code. I
don't see why the appropriate fix would be to ask 32-bit systems to pay a
penalty here instead of changing the reader code. It is certainly
possible to read 4-byte integers on an 8-byte system. You may have to
read and copy the data, but it can be done. If there's a penalty to be
paid, I think it's fair to have the foreign reader pay it.
