I accidentally found a way to duplicate redstone blocks.
Steps to reproduce
1. Place a redstone block two blocks away from the ground
2. Then place a piston on the ground right below
3. After before the piston can extend place any block above it resulting in a duplication of the redstone block.
4. Then update the block that has been pushed up which will then make the block disappear and be replaced by redstone.
I expected the piston to not even extend at all.

Cannot confirm.
When placing two pistons below the redstone block in described manner, the redstone is not duplicated.

BTW: The issue that the piston extends at all is MC-108

After leaving and reentering the world, the second piston is vanished and the redstone blocks is placed in it's original position.

Fake dupe and dupe of MC-631.
