Re: [LAU] Linux audio app design: The nature of xruns

I didn't look at the implementation of QMap, but I don't see how this could work without dynamic memory allocations happening somewhere. In this particular case, I'd expect memory to be allocated for the storage of the map elements, and probably for the content of the QStrings (which are used as map keys) as well. That said, I have no conclusive evidence to prove that any of the xruns I've seen in the past were actually JackMix's fault. The real problem might have been elsewhere. I also use a lot of STL and various Boost libraries in my own JACK projects (including the realtime parts), so I know how painful it can be to figure out which parts of some convoluted template classes are "safe" to use... Dominic PS: the jackmix-0.4.1.tar.gz tarball seems to be gzipped twice, so tar can't open it without gunzipping it first...
