Besides the entry in the UNIX System V Programmer's Release 3 Reference
Manual (307-226), there is a more tutorial summary as chapter 15 of the
UNIX System V Release 3 Programmer's Guide (307-225).  You need not
learn anything about WE32000 assembly language to obtain useful
information such as a traceback of the function calls at the time of
failure.  In fact, sdb is normally used in conjunction with the C
source code, not with the machine language generated by the compiler.
