A suspected memory-leak is definitely the sort of thing that you should report to the authors/maintainers. Even if you think it is triggered by something that you are doing wrong, their program should not respond to that incorrect input by leaking memory. Places like stackoverflow and IRC support channels are really only useful if the answer you are looking for can probably be found in some form of documentation somewhere. For things like suspected bugs or issues with specific implementation, it is best to go to the source (either the actual source, or the responsible devs (which almost always means going to a mailing list). Some particular projects are infamously dismissive specifically of memory leaks, really no matter how much detail you put into your report (Mozilla, I am looking squarely at you), but those should be the minority. Typically if you see run-away memory usage, and are able to provide enough details about what you are seeing, the developers should be receptive. That's been my experience anyway.
