It is omniBroker (ftp://fto.ooc.com/pub/omniBroker/2.0/OB-2.0.4.tar.gz)

  problem in conversion from CORBA_String_var to const char*

It work with egcs-1.0.2 quite good.

Interesting, that now, egcs core dumps, while compiling  with -Ox, x>0
or doing infinity loop  with -O0.
  ( during parsing of CORBA_String_var + CORBA_String_var).

I will try to write small examples, which illustrate the problem during
next few days, if you need.

If you would  look on this problem, please, contact with me.

Yes, of course.

But generation of warning, which coused by specific optimization without
swith for
disabling this optimization, IMHO, is not good behavior  for compiler.

 P.S.  (Hmm, really I'm not shure that it was copy-conversion.
    but I can't to test this, becouse  I can't compile OmniBroker)

So, inform me if you would look on problem.

Thanks.
