+.SH BUGS
+The SIGTRAP signal is used internally by the kernel implementation of
+system call tracing.  When a traced process receives a SIGTRAP signal not
+associated with tracing, strace will not report that signal correctly.
+This signal is not normally used by programs, but could be via a hard-coded
+break instruction or via kill(2).
