copied!<p>Set up your project to use the Windows Low Fragmentation Heap (LFH) using <a href="http://msdn.microsoft.com/en-us/library/aa366705%28VS.85%29.aspx" rel="nofollow">this API</a> at the start of the program. This may fix your problem without more work on custom implementations.</p> <p>Sample code, taken directly from MSDN:</p> <pre><code>#include <windows.h> #include <tchar.h> #include <stdio.h> #define HEAP_LFH 2 int __cdecl _tmain() { BOOL bResult; HANDLE hHeap; ULONG HeapInformation; // // Note: The HeapSetInformation function is available on Windows 2000 with SP4 // only if hotfix KB 816542 is installed. To run this example on Windows 2000, // use GetProcAddress to get a pointer to the function if available. // // // Enable heap terminate-on-corruption. // A correct application can continue to run even if this call fails, // so it is safe to ignore the return value and call the function as follows: // (void)HeapSetInformation(NULL, HeapEnableTerminationOnCorruption, NULL, 0); // If the application requires heap terminate-on-corruption to be enabled, // check the return value and exit on failure as shown in this example. // bResult = HeapSetInformation(NULL, HeapEnableTerminationOnCorruption, NULL, 0); if (bResult != FALSE) { _tprintf(TEXT("Heap terminate-on-corruption has been enabled.\n")); } else { _tprintf(TEXT("Failed to enable heap terminate-on-corruption with LastError %d.\n"), GetLastError()); return 1; } // // Create a new heap with default parameters. // hHeap = HeapCreate(0, 0, 0); if (hHeap == NULL) { _tprintf(TEXT("Failed to create a new heap with LastError %d.\n"), GetLastError()); return 1; } // // Enable the low-fragmenation heap (LFH). Starting with Windows Vista, // the LFH is enabled by default but this call does not cause an error. // HeapInformation = HEAP_LFH; bResult = HeapSetInformation(hHeap, HeapCompatibilityInformation, &HeapInformation, sizeof(HeapInformation)); if (bResult != FALSE) { _tprintf(TEXT("The low-fragmentation heap has been enabled.\n")); } else { _tprintf(TEXT("Failed to enable the low-fragmentation heap with LastError %d.\n"), GetLastError()); return 1; } return 0; } </code></pre>
