Debugging Plugins with "Static Runtime" - Heap memory issues

Audio Plugins
1

When debugging Plugins with "Static Runtime" i constantly  get Heap-issues which appearing while debugging (loading/unloading), they disappear when i use  "DLL-runtime" setting. Is this a problem? (VS2012)

HEAP[Cubase7.exe]: HEAP: Free Heap block 0B2AAE40 modified at 0B2AB6A8 after it was freed

Inside 


void __cdecl _free_base (void * pBlock)
{
        int retval = 0;

        if (pBlock == NULL)
            return;
        RTCCALLBACK(_RTC_Free_hook, (pBlock, 0));
        retval = HeapFree(_crtheap, 0, pBlock);
        if (retval == 0)
        {
            errno = _get_errno_from_oserr(GetLastError());
        }
}
