Strange debug problem

A colleague is trying to debug an RPG IV program -- in particular one
changed module.  The changed module (and most or all of the others) have
been compiled with DBGVIEW(*LIST).  The service program containing the
changed module can be added to the debug environment using F14, and the
source can be displayed by taking a 5 against the module.

However, neither setting breakpoints within the module nor attempting to
step into it with F22 appears to work: the program blithely carries on
to the line after the CALLB.  There are no error messages in the joblog.

The program's behaviour would imply that the code in the module in
question is _not_ actually being executed.

I've spent a lot of time in the ILE debugger, and I've never seen it
behave like this.  Does anyone have any ideas?

We are at V4R3M0, with all objects compiled TGTRLS(V4R1M0).

TIA,

Martin.
