[omniORB] omniORB 2.8.0 and CC -compat=4 on Solaris 2.6 => segfaults

[Landon Boyd]

BACKGROUND:

I'd like to link with omniORB and another library for Sun CC 4.2.  I am using
CC 5.0, so I am using the -compat=4 flag.  I am compiling on Solaris 2.6.

To compile omniORB 2.8.0 with CC -compat=4, I have done the following:

config/config.mk:
  platform = sun4_sosV_5.6

mk/platforms/sun4_sosV_5.6.mk:
  CXXOPTIONS = -compat=4

Modified the following files to look for the __SUNPRO_CC_COMPAT macro.
  include/omniORB2/CORBA_sysdep.h
  src/appl/omniNames/log.cc
  src/lib/omniORB2/orbcore/tcpSocketMTfactory.cc
  src/tool/omniidl2/include/ast_decl.hh

For example, a directive like this:

#if (__SUNPRO_CC < 0x500)

was changed to this:

#if (__SUNPRO_CC < 0x500 || __SUNPRO_CC_COMPAT == 4)


PROBLEM:

omniORB compiles fine, but when running the example programs I get segfaults.

For example, if I run eg2_impl and then eg2_clt, eg2_clt runs successfully,
but then the server segfaults.  Trace output is included at the end of this
message.

Has anyone seen this problem, or is there any insight as to how I might
get around it?

Please be sure that I am included as a recipient of any replies as I am not
subscribed to this list.  Any help would be greatly appreciated!
