Hanging Cout!! Help!! C/C++/ESQL/Informix/Unix/MQM/Solaris

Hi,
Could someone please help me?

My program hangs in a simple COUT statement!! What seems to be the problem??
I've tried different combinations of compile/link/runtime options, nothing seems to work. This is frustrating!

There is really nothing complicated here.
I've simplified the scenario and created three simple programs (codes below).
These are my objects:
1. tstmainc.ec - Main Program in C
2. tstsubc.c - Sub Program in C (simple printf)
3. tstsubcp.ec - Sub Program in C++ (SQL commands and Cout).

We are using:
- Informix 731
- uname -a = > SunOS gfxdev 5.6 Generic_105181-23 sun4u sparc SUNW,Ultra-2
- cannot remove mqm libraries (real program uses them)

Any help will be greatly appreciated!

Thanks!
