MCH3602 - Pointer not valid

I'm not sure exactly where to ask this, so I'm cross posting on Midrange-L
and Domino-L. We are moving from one box running V5R2 to a new box
runnning V5R4. We have done a backup on the old box and then restored on
the new box, and we're now testing things out.

My job is to test some Domino applications that use ODBC to get
information from DB2/400, and I've run into something that seems strange.
Straight SQL queries seem to work fine, but if I call a stored procedure
and pass it a parameter, I get a MCH3602, "Pointer not valid for requested
operation", error in the job running in QSYSWRK.

The thing is, the first program (the once called from the Domino
application) runs fine -- it accepts the parm, removes the null terminator
and pads it with spaces, and then calls a CL program passing the cleaned
version as a parm. The CL program then bombs the first time it tries to
use that parm.

The program was a CLP, and I discovered that if I compiled it as a CLLE
(no code changes) it worked fine, and if I then compiled it as a CLP
progam again it bombed. The CL program calls an RPG program, and the same
thing happened -- the CLLE would call the RPG program fine, but the RPG
program would bomb; when I converted the RPG to RPGLE and recompiled, it
ran fine.

I guess I can get everything to work by recompiling all the affected
programs, but the whole thing seems very strange. Does anyone have any
idea what might be going on, or if there's some other solution that
doesn't involve recompiling everything? I'm a little worried that this
might be a symptom of a bigger problem that I should be looking into . . .
.

Thanks very much,
