--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, but this destructive modification of something we don't unshare doesn't
work. Either we have to always wrap statement lists but then we're back to
the compare-debug issue or we somehow fix the destructiveness on the
stmt list node itself - like not setting it's type to void or marking it
as having side-effects (why do we do this anyways, in voidify_wrapper_expr?
is that for debugging?), we'd also need to leave the final value in the
stmt list for a possible second gimplification round...
Maybe the best thing is to kill off the debug stmts when they would cause
a stmt list to appear and revert the previous fix.
