Exception at 0x751fc52f, code: 0x71a: , flags=0x1 (execution cannot be continued) (first chance)

Question

I get the error in subject line when I debug my Qt application (using Qt Creator 3.6.0)

I don't get it when I build and run but only when I debug it. It seems like because of this, my debugger is acting funky as well, sometime it doesn't step into the code, other time it does, specially when restart Qt Creator.

More importantly there is no clue where this exception is happening. How can i get to this exception and possibly have the debugger stop where it is occurring?
