Multiple sub breakpoints where hat functions are

Question

Our C++ based app has a very annoying behavior whereby it takes multiple "step over" commands to get over the line of code.  If you look at the break points window for the line you will see a + symbol on the left and if you open it you see multiple sub break points.  I don't see this same behavior when running through the C++ sample apps.

Can someone tell me why this is happening, and how to stop it?

Regards, Guy

Hello,

 

Would you please show us the detail codes about this issue, like which code you try to debug and which line do you set the break point.

 

Best regards,

Jesse

Here is an example.  If I try to step over line 185, it will take me 3 steps before I get over it.  Interestingly, we have a test runner project that runs this same code and if I get to this same line in there the BP is a single item rather than 3 like it is here.

Though I am showing a BP here it is irrelevant to the actual problem which is just that if you step over code with the -> you will have to step multiple times to get over the line.  The BP just gives you a visual example of the behavior.

Nothing here?  There must be a way to disable this.

Answer 6

Yes, and I have investigated further.  Our project that exhibited the behavior is set to debug in mixed mode and the project that did not exhibit the behavior was native only, I switched the native only project to mixed mode and it started doing the multi-step/sub-bp thing, so it appears that it only happens when debugging in mixed mode.

Thanks Guy,

I've asked our tools folks to take a closer look at this for you. Hopefully one of them will have some insight.

There are numerous issues when debugging Windows Store apps with the mixed mode debugger.  The good news is that this experience is being greatly improved in the Visual Studio 2012 Update 1, which is currently available as a CTP.
