HELP: Sunview

[Carlos Carrion]

I'm having problems with the panel_each_item,panel_end_each macros.  I've
tried both the macros and writing out the code to accomplish the same
thing.  I produce an executable so not including .h files is not the
problem.

I'm using oregon's C++ compiler on a Sun 3/80.  All the sunview functions
are declared with C linkage and are called by member functions of C++
classes or as simple non-member functions.

Here's the error message from dbxtool:

signal SEGV (segmentation violation) in panel_get at 0xbaf78
panel_get+0x22:		movl	a0@(0x24),a0

The Sunview routine (with the explicit code written out) follows:

void remove_item_with_label(pn,label)
Panel pn;
char* label;
{
	Panel_item pi;
	char* get_window_name();

*** dbxtool points at the line below ***
==>	for(pi=(Panel_item)panel_get(pn,PANEL_FIRST_ITEM);pi;
		pi=(Panel_item)panel_get(pn,PANEL_NEXT_ITEM))
	{
		if(!strncmp((char*)panel_get(pi,PANEL_CLIENT_DATA),label,strlen(label)))
		{
			/* found button */
			panel_set(pi,PANEL_SHOW_ITEM,FALSE,0);
			panel_destroy_item(pi);
			return;
		}
	}
}

A "dump" command produces the following:
label = 0x1fba58 "rtg"
pi = 0x1fcd10 ""
pn = 0x1fba44 "rtg"

A "where" command produces:
