------- Comment #4 from jv244 at cam dot ac dot uk 2009-09-19 18:27 -------
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
