; The intent is to test discriminator 1 generated for both line #4 and #5.
; The instruction sequence in the final binary is:
; line 4 discriminator 0
; line 5 discriminator 0
; line 4 discriminator 1
; line 5 discriminator 1
; We need to ensure that the discriminators for the last two instructions
; are both 1.
