One more thing with -Os the compile time is fine in 4.0.0 because we don't duplicate final blocks.
I am not marking this as a regression because we produce better code with the mainline than 3.4/3.3
for this case. Basically the problem can be fixed by making gcc not inline a function into itself or
making the decting if a function does not throw better.
