Hi experts,

A bit background: I am integrating a C module to a c++ framework. The
C module is single thread, while c++ frameowrk multiple creates
threads for each connector it creates. The pipes are being used to get
notifications from the c++ threads.

While regression testing with single connector, the application works
great! But with 2 connectors, it locks.

When hacked with gdb, it is the main thread that looks locked (ps -m
shows it in Running state and rest of the c++ threads in Sleeping
state). The next step shown is part of STL always. (There is no other
thread accessing data in main thread).

The regression test of creating 2 connectors, in a sample c++
application, works just fine.

I am a bit lost here as, why the main thread is getting locked in STL?
Is there any issues with STL? Do the versions of libraries of c++
modules have something to do with this?


I am using -DLINUX -DPTHREADS -DMULTITHREAD -D_REENTRANT options in
g++.
