Could it be that the process was started with SIGALRM inherited as ignored?  
Generally it is a bad idea to start unrelated child processes with signals in 
an ignored state, when the child isn't expecting it.  Does adding a call 
to "signal(SIGALRM,SIG_DFL);"  prior to the alarm() in the test case help?
