I've got a strange issue in which one particular OPM program (OPM RPG,
if it makes any difference), when running on one particular box (the one
on which it was compiled), is unable to access the INFDS of its display
file, and blows up with a "pointer not set" error if it attempts to do so.

It sounds like storage corruption. The OPM RPG compiler defines the
INFDS as based on an internal pointer. If that pointer gets corrupted,
then any access to the INFDS would fail with a pointer not set.
If you pass parameters to some other program, maybe that other program
did change, to expect larger parameters.
Assuming I'm right, you might be able to narrow down where the
corruption is happening by adding several statements that use the INFDS
into your program. Code a few COMP statements like the one below into
your program, and run it. When it fails on one of them, add the COMP
statement at every statement between the previous good one and the
failing one. Run the program again, and you should be able to see
exactly where the problem starts.
