gcc45-pr42719.patch
Big hammer patch to reset the debug stmts because of which we'd return true
from trivially_conflicts_p when we'd otherwise return false.
Wonder if we don't have other options though (ignore the debug stmts, then do
something about them) and how much it will affect real-world code.
