+Your setup is interesting -- you have GNU textutils 2.0.22, released\r
+2002-07-20 (i.e. 13.5 years ago) and then gdb 7.4. I just run this\r
+test file on Scientific Linux 6.2 (gcc 4.4.6 and gdb 7.2), and the\r
+tests passed without problems.\r
+\r
+Apart from a few special cases, no typecasts should be added lightly\r
+to the code -- be it at innocent-looking as it can be. Those impedes\r
+the possibility for compiler (etc.) to do type checking.\r
+\r
+So, in this case, if you're the only one seeing this problem I'd suggest\r
+you tolerate the problem (by using private patch) (you could also dig\r
+deeper if interested). If this "problem" is (were!) more widespread,\r
+*and* unfixable in reasonable manner this thing like this typecast\r
+could be applied -- which would also mean this test system would\r
+be a bit less robust as it is now...(*)\r

+\r
+(*) imo these are hard facts, but someone(tm) may consider these as mere\r
+opinions...\r
