Hello everyone, I am experiencing a memory leak while using pool_allocator with std::vector. I am detecting this with _CrtDumpMemoryLeaks() on MSVC8. The full program listing is at the end of the program. The leaks reported are: Detected memory leaks! Dumping objects -> {122} normal block at 0x00356518, 520 bytes long. Data: < e5 e5 $e5 (e5 > 1C 65 35 00 20 65 35 00 24 65 35 00 28 65 35 00 {121} normal block at 0x003563D0, 264 bytes long. Data: < c5 c5 c5 c5 > D4 63 35 00 D8 63 35 00 DC 63 35 00 E0 63 35 00 {120} normal block at 0x00356308, 136 bytes long. Data: < c5 c5 c5 c5 > 0C 63 35 00 10 63 35 00 14 63 35 00 18 63 35 00 Object dump complete. This could be due to a static object being destroyed after main() returns but I couldn't know that without knowing the implementation of pool_allocator. I have tried getting mem checkpoints at the beginning and end of main and detecting the leaks that way which I *think* would get around static objects but without any difference.
