Mr. Linares,

Incredible the calls that are made to hb_xbfree.

Dear Antonio,
Can you please explain what these tests are about?
Best regards,

Dear Otto,

we have found that building Harbour with these flags:

set HB_USER_CFLAGS=-DHB_FM_STATISTICS_OFF -DHB_FM_WIN_ALLOC

the resulting libharbour.dll manages memory much better, as we use the standard Windows API LocalAlloc(), LocalRealloc(), LocalFree(), etc to manage the memory on Windows

Also, modifying mod_harbour's entry.c this way (two calls to OutputDebugString()) makes memory liberation work much better:

Code: Select all  Expand view

#include <Windows.h>
#include <hbapi.h>
#include <hbvm.h>

static void * pRequestRec;

HB_EXPORT_ATTR int hb_apache( void * _pRequestRec )
{
   int iResult;

   pRequestRec = _pRequestRec;
 
   hb_vmInit( HB_TRUE );
   OutputDebugString( "after hb_vmInit()\n" );
   iResult = hb_vmQuit();
   OutputDebugString( "after hb_vmQuit()\n" );
   return iResult;
}  

void * GetRequestRec( void )
{
   return pRequestRec;
}

HB_FUNC( AP_ENTRY )
{
   hb_apache( NULL );
}
