Visual Studio - can be a breakpoint called from code?

Question

I have a unit test project based on UnitTest++. I usually put a breakpoint to the last line of the code so that the I can inspect the console when one of the tests fails:

  n = UnitTest::RunAllTests();   if ( n != 0 )   {   // place breakpoint here         return n;   }   return n; 

But I have to reinsert it each time I check-out the code anew from SVN. Is it possible to somewhat place the breakpoint by the compiler?:

      n = UnitTest::RunAllTests();       if ( n != 0 )       {       // place breakpoint here     #ifdef __MSVC__         @!!!$$$??___BREAKPOINT; #endif         return n;       }       return n;

Use the __debugbreak() intrinsic(requires the inclusion of <intrin.h>).

Using __debugbreak() is preferable to directly writing __asm { int 3 } since inline assembly is not permitted when compiling code for the x64 architecture.

And for the record, on Linux and Mac, with GCC, I'm using __builtin_trap().
