About VS2013 single-step debugging into the Disassembly program problem

When writing a simple program of sparse matrix arithmetic, it is found that the subroutine cannot be entered when stepping debugging, but instead shows the disassembly program.

Many times after the test without the choice of Baidu-related issues, found the following options:

Method One: Rebuild the solution, and then Debug.
Method Two: Menu-Tools-Options-debugging-"show disassembly when source code is not available"
Method Three: The tool-"Options-" debugging-"general-" requires that the source file and the original version of the exact match to cancel out.
Method four: Project-"Properties-" c/c++-"General-" Debug Information format confirmation is not disabled. Try using Zi

After trying to find out, there is no way to resolve the existing problem, considering that the disassembly is not possible because the subroutine's debugging process cannot be displayed. Why can't I show it?
I looked again at my program and found that an array of maxsize= 12500 was initialized.
So the conjecture might be that the array is too large to display, try to define maxsize as 1250, or the definition of 125 succeeds.

For your reference only.
