Memory leak in deque - is this a bug, a known issue, or am I doing something wrong?

[Boris Glick]

Hello! The following causes a memory leak report in VC 6.0. It seem to
happen only for this specific object size (16 bytes) and count. Am I doing
something wrong? Did anybody else run into this?

Thank you!

#include <deque>
#include <crtdbg.h>

struct MyClass { int a, b, c, d; };

int main(){
// Turn on memory leak detection
_CrtSetDbgFlag( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
_CrtSetReportMode( _CRT_WARN, _CRTDBG_MODE_WNDW
| _CrtSetReportMode( _CRT_WARN, _CRTDBG_REPORT_MODE ) );

// Build and fill a deque
std::deque<MyClass> md;

for(int i = 0; i < 128; i++){
MyClass mc = {0,0,0,0};
md.push_back(mc);
}
return 0;
}

Apply the <deque> fix (and the others too!)

The memory leak disappears...

Thank you so much Tom! I tried the fixed <deque> header and the leak goes
away. It looks like that particular fix has been there, but not in VC,
since October 1999 (!!!)

It's a long story why it hasn't shipped in any SPs for VC6, but VC7+
has a (probably) bugfree version of <deque>.
