    *************************************************************************
    The SIGTERM termination is coming about because ch_t27 is spining
    forever in this loop (sigcon3.c):

    while(!sig_recvd)
    i++, j++;

    This is because sig_recevd is not declared as volatile. Due to a
    more aggressive optimization default behavior, our C compiler
    simply optimizes the test of sig_recvd away.

    When sig_recvd is declared as "extern volatile int sig_recvd"
    in sigcon3.c, the program works fine.

    We believe this to be a test suite defficiency.
