further reduced, looks more like a middle end issue to me:

      IVFAIL=0
      ASSIGN 1263 TO I
      GO TO I, (1262,1263,1264)
 1262 ICON01 = 1262
      GO TO 1265
 1263 ICON01 = 1263
      GO TO 1265
 1264 ICON01 = 1264
 1265 CONTINUE
41260 IF ( ICON01 - 1263 )  21260, 11260, 21260
11260 IVPASS = IVPASS + 1
      GO TO 1271
21260 IVFAIL = IVFAIL + 1
 1271 CONTINUE
      WRITE (6,*)  IVFAIL
      END
