; In the code below, %0 is known to be equal to the content of @c (constant 0).
; Thus, in order to save a scalar dependency, forward-optree replaces
; the use of %0 in Stmt_lor_end93 by a load from @c by changing the
; access find from a scalar access to a array accesses.
; llvm.org/PR48034 describes a crash caused by the mid-processing change.
