[ptp-dev] Null pointer exception when looking for function definition

[Dave Wootton <dwootton@xxxxxxxxxx>]

I have the following program
#include
<stdio.h>
int
i;
int
main(int
argc, char
*argv[])
{
         
printf("Hello\n");
         
sub();
}

int
sub()
{
        i
= 0;
        printf("In
sub.\n");
}

If I select the reference to sub() and
hit F3, the definition of sub() is highlighted. If I select the first reference
to printf() and hit F3, I get the following exception
