Re: ofstream and locales: how do they use heap memory?

Hi,

I have unit tests which I test for memory leaks. At the beginning and
at the end of a unit test I'm checking for the memory allocated on
heaps. If the number of bytes allocated on heaps differ, then a
memory leak is reported. However, an implementation of a standard
library can allocate or release memory on a heap during a test, which
will trigger a false alarm. One example of code that can cause a
false alarm is this one, which is reported to "leak" 96 bytes:

{
  std::ofstream("test");
}

I'm attaching below two programs that test this block. They are for
VC++ 2005.

PROGRAM 1 executes the block above, and checks for differences in
heaps. This is what it prints:

Difference of 96 bytes
Difference of 3 blocks

PROGRAM 2 also deals with this block, and it helped me with checking
the memory allocations and deallocations. I set the breakpoints in
the CustomAllocHook function and meticulously gathered the data shown
below as ALLOCATIONS AND RELEASES. It seems that heap allocations
have to do with locales.

Finally I'm getting to my question. Can I do something so that I
don't get these false reports on memory leaks? Like reinitializing
the part of the standard library that deals with locales?
