[omniORB] HPUX/PA-RISC 64-bits porting

[Andrew Novikov]

Hello,

During my HP-UX porting effort I came across the following problems. 
First of all I was able to build omniORB 4.0.3 on HP-UX 11.11 using aC++
A.03.33. In order to do it I applied a simple patch which fixes
compilation options (it is attached to the e-mail) and ran "./configure
CXX='aCC +DA2.0W -AA' CC=cc --enable-static=no && gmake". After some
experiments with the fresh build I discovered some locking problems
inside the omniORB that were fixed by HP-UX patches PHCO_29960 and
PHCO_27633 (it may sound easy, but it took a lot of time to understand
where was the root of troubles). And then the next problem arose. Under
some circumstances services that use omniORB produce segmentation faults
inside the omniORB. These segmentation faults appear in
src/lib/omniORB/orbcore/giopImpl12.cc:1404 and are caused by the
following code in src/lib/omniORB/orbcore/giopServer.cc:642:

connectionState* cs =  new connectionState(conn,s);

connectionState** head = &(pd_connectionState[((omni::ptr_arith_t)conn)%
						connectionState::hashsize]);
cs->next = *head;
*head = cs;

The code above produces an endless loop in the
omni::omniInterceptorP::clientSendRequest (a list) and it causes
omni::omniInterceptorP::visit() in giopImpl12::marshalRequestHeader() to
segfault. Strange is the fact that such a situation never occurs on
Linux...
So, what is the purpose of giopServer::csInsert() and why does it behave
so strange?

Regards,
Andrew Novikov
