Ah good, an insult. I win.

Microsoft agrees with me on the definition of a memory leak. Given the
following program:
char* p = new char[4242];
int main()
{
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
}
The following is output on program termination:
Detected memory leaks!
Dumping objects ->
{68} normal block at 0x007C4A20, 4242 bytes long.
Data: < > CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD
Object dump complete.
Well valgrind and dbx agree with me:
dbx:
Checking for memory leaks...
Actual leaks report (actual leaks: 0 total size:
0 bytes)
Possible leaks report (possible leaks: 0 total size:
0 bytes)
Checking for memory use...
Blocks in use report (blocks in use: 1 total size:
4242 bytes)
Total % of Num of Avg Allocation call stack
