Fix panic on negative slice indices that underflow after adjustment ( #2646 )
...
sliceArrayOperator adjusts negative indices by adding Content length,
but does not clamp the result. When the absolute value of a negative
index exceeds Content length (e.g. .[-99999:3] on a 3-element array),
the adjusted index remains negative and causes an out-of-bounds access
in the Content slice loop.
Extract the adjust-and-clamp logic into clampSliceIndex and use it for
both index positions.
Reproducer (panics before this fix, returns full array after):
echo '[a, b, c]' | yq '.[-99999:3]'
