System V Pic command on 90x

[Rick Kamicar]

I encountered this problem last friday and found the following:

The problem is caused as follows:

troffgen is called from picy.c (generated by yacc) as:

->			yyval.o = troffgen(yypvt[-0].i);


where yypvt is declared as YYSTYPE.  The code for troffgen is:


->	obj *troffgen(s)	/* save away a string of troff commands */
->		YYSTYPE s;
->	{
->		savetext(CENTER, s.p);	/* use the existing text mechanism */


But, picy.y sends the int element of YYSTYPE --NOT the actual structure!
The simple changes below (there are 2) solve the problem...


->	obj *troffgen(s)	/* save away a string of troff commands */
*->		char *s;
->	{
*->		savetext(CENTER, s);	/* use the existing text mechanism */
