If this sounds painful, it was. I couldn't find complete advice on this subject, other than partial confirmation that Intel tests only VS installations made on clean systems not upgraded in place. Thanks Tim, I agree it does work fine with update 1 and thanks for the detailed info on your update on this.

Hi Shi, I am not able to reproduce the issue that you're seeing. I wonder if there's any environment issue on your end or if the upgrade went smoothly or an integration issue with VS that Tim pointed out?

I can then try to locate a system with exact configuration and try out to see if I can reproduce, thanks.

If command line works, it is an issue of VS integration. Do you have old version of compiler integrated into Visual Studio? To get the version of compiler used in your current project, check as below:. Great, that's what Shenghong and I had concluded on this offline if the command line worked and it's good to know that was the issue.

In the attached for loop: the first iteration works well, but for the second iteration the number ends up with 0 in it. strinfocus gets the right value,  string stream issues.
In fact, when streamstring calls str , it returns a temporary string object, which will be destructed along with the function return.

Thus, these strings cannot be referenced after the expression evaluation, and the memory will be retrieved or might be overwritten.

Although in some cases for example, delete line 20 from example 2 , this memory might not be overwritten and we can still read out the strings, but the accuracy of the read result is not guaranteed. Let's modify example 2 as below: When we want to manipulate on this string object for example, to create corresponding C string , we must be very careful about this trap that might cause unexpected results.

Since the memory of the temporary object might not be overwritten so that this trap might not expose, but the usage does not guarantee the accuracy of the results. So to avoid wrong results, you should make sure to use this function correctly.
