HELP !,
Has anybody port 'mextra' (1983 VLSI tools UCB) from a VAX11/780
running 4.3BSD to a Sun3/160 running UNIX3.5?. I'm working on that
and I got stuck. 

1. I'm able to compile mextra but when I run it I get a 
'segmentation violation ' fault.

2. Using dbx...
	(dbx) running mextra nor2
	signal SEGV (segmentation violation) in strlen at 0x184c8
	strlen+8:	tstb	a1@+

3. Checking my stack...
	(dbx)where
	strlen(0ffffffff, 0x0, 0x9582, 0x0) at 0x184c8
	CleanUp(),
	ReadCif(FileName=0x40f48 "nor2.cif")
	main(argc=2, argv = 0xefffc7c, 0xefffc88)

4.  CleanUp calls EnumerateSymbol with the following arguments :

    EnumerateSymbol(-1,NIL,check,NIL);

5. EnumerateSymbols is defined as :

	EnumerateSymbol(n,trans,f,path)
	int n;
	transform *trans;
	int (* f)();
	char *path;
	{
		int len;
		/*other local variables*/

		len = strlen(path) + 1;
                ^^^^ Here is where my program crashes ^^^^

6. I tried
		len = (int)strlen(path) + 1;
  but doesn't do anything.

Does anybody have any idea of what is going on or how to tackle this problem?
Any info will be appreciated.
