while preparing the example I found the source of the problem. We have
to block all signals for some reason. The handling for

signal (SIGTHR, SIG_IGN);

seems to have changed. The moment I remove above's line from the code,
the program works. There is no difference when the programs runs on
machines prior mid November 2014.

Thanks for your help. Simplifying the program brought me to the
solution. 

Do you want the example?
