stdlib: Fix array bounds protection in insertion sort phase of qsort
|
||||
|
||||
The previous check did not do anything because tmp_ptr already
|
||||
points before run_ptr due to the way it is initialized.
|
||||
|
||||
Fixes commit e4d8117b82065dc72e8df80097360e7c05a349b9
|
||||
("stdlib: Avoid another self-comparison in qsort").
