Hi Guys,
Whilst looking at PR 747 I discovered that gprof's -C switch was
causing a seg fault. It appears to be a simple case of a missing
line of code - a sorted table was being created but the code to walk
through the table was not initialising the pointer.
The attached patch fixes this problem and I am going to check it
into both the mainline and the 2.16 branch.
Cheers
Nick
