Well, here is the latest from Bugland....
I take my program into sdb.  I edit my main microcode parser with
'e g.tab.c'.  Here is what happened in toto:

$ sdb sdbgm
No core image
* e g.tab.c
'g.tab.c:'		/* or whatever the standard message is */
* /pending/
	/* one line containing pending */
* //
	/* another line containing pending */
* //
Memory fault - core dumped
$ rm core;sdb sdbgm
No core image
* 2200w
Memory fault - core dumped
$ /* at this point I edited the file and found that what I was
	looking for was at line 1977 */
$ rm core;sdb sdbgm
No core image
* 1977
Memory fault - core dumped
$ rm core;sdb sdbgm
No core image
* 1900
	/* line 1900 apears here */
* 1950
	/* line 1950 appears here */
* ^D
	/* a few more lines */
* ^D
1959:	/* line 1959 */
1960:	/* line 1960 */
1961:	/* line 1961 */
Memory fault - core dumped
$

Anyone experienced anything like this?
And, as several people have asked, I am running y.tab.c through
'cc -EC' into g.tab.c to take care of yacc's #line directives that
confuse sdb.
