This is caused by inconsistent use of SIGCLD and SIGCHLD within sendmail.
Because these are now separate signals for the same event, two different
signal catchers get set up.  It then becomes a race as to which handler gets
the signal.  The fix is to change all occurences of SIGCLD to SIGCHLD in the
sources and add the conditional

#ifndef SIGCHLD
# define SIGCHLD	SIGCLD
#endif /* !SIGCHLD */

to useful.h after all #include statements.
