You have some extensions loaded in php.ini, right?
Which ones are those? What if you don't load them?

The problem is still there. Nothing has changed. 
I performed the same 2 tests. 

1. LoadLibrary and FreeLibrary - 200 cycles = 50MB leak
2. HttpExtensionProc - 1000 calls = 500kB leak

Please, let me know how can I help.

Still the same. Btw. what I testing now is not the COM object issue but
simple HttpExtension call which leaks the memory. Each call to the
ISAPI module leaks some memory. Tell me. Thanks

I was wrong about the _DllMain@12 it is called by Windows
automatically. However I have found for instance this.
If you load the ISAPI module and free it in a cycle again it does not
free the memory.
for ($i=0;$i<1000;$i++)
{
  lh = loadlibrary("...isapi.dll");
  freelibrary(lh);
}
After 200 cycles the process consumes 50MB. I don't think that should
happen. What is wrong?
