The problem is a result of dynamically loading threads libraries.  The 
Solaris threads libraries (libthread and libpthread) are intended to be 
loaded only at the start of execution.  If you dynamically load them, 
the results are undefined.

The specific problem you have is a result of mixing the alarm(2) 
implementation in libc with the one in libpthread.  They are not compatible.
