Please see PR36079 that introduced -mcld. When the sample test program provided above was compiled with gcc 4.4, it did not generate the stos instruction. However, each of 4.5, 4.6 and 4.7 did generate the stos instruction. Given this, I'd like to clarify your answer. If I may summarize: 4.3.0 stopped using cld. After cld was not used, an error existed in versions 4.4, 4.5, 4.6 and 4.7. The error was fixed in 4.8. You have backported the fix from 4.8 to 4.7. You did not backport to 4.5 and 4.6 because they are closed. You do not state, but I infer that 4.4 is also closed. Do you have an idea why the test case does not demonstrate the error on 4.4? Is there a test case that will demonstrate the error on 4.4? Thanks for your help and patience
