LLVM r80583, compiled with LLVM-GCC with -O3.

Test program:

int main(void)
{
    llvm::APFloat af(0.0);
    af.convertFromString(llvm::StringRef("2.71828", 7),
                         llvm::APFloat::rmNearestTiesToEven);
    return 0;
}

"p" is incremented, then assigned back to the beginning of the string.
