That bug is not a duplicate of MC-10755. Mine is about scren, while the other is about block mining.
I did what you said, but it doesn't crash for me.
I confirm that the FOV change is delayed about the sprinting status.
I confirm that it can be reproduced in younger versions. In 1.5.2 and 1.5.1, it still works.
And it is not only gold apple, any regeneration item does this, but it's less visible (regeneration 2 is pratically invisible).
That is to say that golden apple is dangerous in a PvP, if enemy has a rapid fire mouse.
It is not a bug. If you looked at the changelogs (eg in Minecraft Wiki), you could see that it is intentional. Swords are now unable tobreak blocks in Creative.
