_crtBreakAlloc in VS2017

I try to find out memory leaks using CRT. I'm using Visual Studio 2017 Community. I followed the official help, but its not working.

I tried different inputs in Watch window. That's what I get:

_crtBreakAlloc identifier "_crtBreakAlloc" is undefined

I tried suggestions I've found in another question and got the same results:

(int*){,,ucrtbased.dll}_crtBreakAlloc identifier "_crtBreakAlloc" is undefined

(int*){,,ucrtbased.dll}__crtBreakAlloc identifier "__crtBreakAlloc" is undefined

Debug build, runtime library Multi-threaded Debug DLL (/MDd).

I tried calling function _CrtSetBreakAlloc and it works.

So is re-compiling and calling this function the only option? Or am I missing something obvious?

Solution

  • Try:

    {,,ucrtbased.dll}_crtBreakAlloc

    Make sure symbols are loaded (Tools / Options / Debugging / Symbols).
