>From today's .vars dump:
# BLOCK 4
# PRED: 3 [95.0%] (false,exec)
<L3>:;
c = c - 1;
ivtmp.54 = ivtmp.54 - 8;
if (c != 0) goto <L2>; else goto <L16>;
# SUCC: 3 [75.0%] (dfs_back,true,exec) 10 [25.0%] (loop_exit,false,exec)
(...)
# BLOCK 10
# PRED: 4 [25.0%] (loop_exit,false,exec)
<L16>:;
buf[0] = (unsigned char) ((signed char) c | 64);
len = 1;
goto <bb 9> (<L9>);
# SUCC: 9 [100.0%] (fallthru,exec)
So this is still not fixed.
