As Carl mentioned, just use +O2 for that one source.
Using +Onoinline may work too.

This is probably saying you have too many trys?  I've seen this on 10.20
and I thought they increased the limit.

Hmm, looking at the code indicates they increased the limit, so it
may be an HLO bug.  (Ah, the limit one was Error 5208, and the limit is 300.)

(Most likely because you got that error.  ;-)

     ^^^^^^^^^^ ^^^^^^^^
Why are you using -L/usr/lib for a +DD64 link?  Because of some ISV lib
is in the wrong place?
Also, libraries should be at the end of the link line.

 ^^^^^^^^^^^       ^^^^^^^^^^^
Did you mean +DAportable?
If you are using HP's supplied tools.h++ you can't use -DRW_NO_STL.
