[Dpcl-user] dpcld dies AIX 5.2

[Timothy H. K. <tk...@sd...>]

I am getting a dpcld crash when I try to run the "hello" example while 
eut_hello hangs.

Any thoughts on what might be going wrong?

I built dpcl 3.3.4 from source on AIX 5.2.  To try to track down the
problem I added

 -g -DDEBUG_CLIENT

to the GLOBAL_CFLAGS and GLOBAL_CXXFLAGS in rules.mk.aix.in.

I then also changed

CC = @CC_R@
CXX = @CXX_R@

I ran dpcld via a wrapper using dbx and got the following:

I also ran eut_hello using dbx and found it is hung in
