This is caused by 'x' being emitted as if it is still accessed via the frame
pointer. This is the relevant snippet form the cvdump output:

(000024) S_GPROC32: [0001:00009F10], Cb: 0000004F, Type:             0x1003, D
main
         Parent: 00000000, End: 00000094, Next: 00000000
         Debug start: 00000008, Debug end: 0000004A
