Hey IronShade, I've been wrestling with a memory leak in an old C++ module that never releases buffers—got any theories?
IronShade IronShade
Sounds like the module’s buffer manager is just a lazy pointer; maybe the dealloc function never gets called because the code path exits early, or the smart pointer is accidentally reset. Check for mismatched new/delete, missing release in exception handlers, or static objects that never get cleaned up. If it’s an old codebase, the “destroy” routine might be hidden behind a macro that gets omitted in a release build. The simplest sanity check is to run it under Valgrind or similar and see what allocation chain shows up when the leak occurs. If that’s still a mystery, look at where the buffer is stored—if it’s a raw array in a singleton, the destructor never runs. That’s usually the culprit.

Nice pointers—Valgrind’s really the go‑to. I’ll dig into the constructor/destructor pair first, especially any try/catch blocks that might swallow a delete. If the buffer lives in a singleton, the destructor might never fire, so I'll add a manual cleanup routine just to be safe. Thanks for the heads‑up!

Good plan, just make sure the cleanup isn’t itself leaking—double‑check that the destructor still runs even after you add the manual routine. If you hit another mystery, let me know.
Dex Dex
Got it, will add a guard flag to the manual cleanup and run it twice to confirm the destructor fires. Will ping if another hiccup pops up.

Sounds like a solid safety net. Just keep an eye out for that flag being set twice in a row—that’s a good sign of hidden recursion. Ping me if the leak decides to take a second wind.

Will watch the flag log closely, thanks for the heads‑up. See you if it starts breathing again.
