[omniORB] omniORB-4.1.0 on QNX6.3.2(more details)

[Hajime Saito]

Hello,

As my previous email was rather lacking in detail I have decided to add 
some more.

I compiled omniORB-4.1.0 with the following set in mk/beforeauto.mk.

The configure script found these:
UnixPlatform = 1
Threadsystem = Posix
Compiler_GCC = 1

My modifications were:
QNX=1
x86Processor = 1

together with:
ifdef QNX
IMPORT_CPPFLAGS += -D__qnx__
OMNITHREAD_POSIX_CPPFLAGS = -DPthreadDraftVersion=10
OMNITHREAD_CPPFLAGS = -D_REENTRANT
OMNITHREAD_LIB += -lsocket
endif

When I run examples/echo/eg1 with ORBtraceLevel set to 100 I get the 
following output

Abort (core dumped)
-----------------------------------------------------------------------------------------
When I take a look at the core using gdb I find that after Terminate() 
gets thrown from giopServer::notifyRzNewConnection, it causes a SignalKill.

I have tried running omniNames -start and trying to get a list of bound 
servers in the same PC using nameclt. In this case, nameclt runs 
successfully but omniNames segmentation faults with tcpConnection::Recv 
returning -1 due to rx being 0 and errorOnReceive raising CommFailure.

All this seems to suggest that there is something going on when 
communications are being shutdown.

Does anyone have a clue what to do from here? I would be glad of any 
information anyone may have.

Best regards,

Hajime Saito
