There is no backtrace in this bug or any statement of the point in such a 
backtrace at which you think an invalid argument has been passed to a 
function that should not have been passed there.  C_MAYBE_CONST_EXPRs are 
created at various stages in the front end and are lowered by 
c_fully_fold, so none should exist by gimplification.  If the 
C_MAYBE_CONST_EXPR is being seen during gimplification, that's a front end 
bug.  Otherwise, non-front-end code dealing with trees needs to accept 
them just like any other front-end-specific trees.
