Now that the mailing list is active again, any luck with the memory leak on windows? I posted a message about this a while ago, but i guess the conversation sort of trailed off. Here were the messages

Here were the messages I ran your program through Purify, and can't see any of those memory leaks. Well, except for some memory from DLL loading (544 bytes) and from DirectSound that is apparently not released (4 blocks of 22 bytes each, in waveOutMessage), but nothing related to Audiere directly.

Hmm.. What version of Visual Studio are you using? I'm not familiar with Purify, but can you just open up task manager and read me the "Mem Usage" of audtest.exe at every cin.get() in my program?
Basically, the memory usage should stay the same throughout the program. However, when i run it, it starts out at about 4,000k, then jumps up to 8,000k due to memory leaks. Only when the Device gets set to NULL does the memory get freed.
Thanks

"Mem usage" is actually not a very good way to test for the memory
requirements of an application. It represents the working set of an application, which can depend on your operation system, its loading strategies, the load of the system, etc. "VM Size" is generally more useful. http://en.wikipedia.org/wiki/Working_set http://en.wikipedia.org/wiki/Virtual_memory http://en.wikipedia.org/wiki/Page_file http://en.wikipedia.org/wiki/Address_space On 4/23/07, Jacky J <flamuss@...> wrote: > Hmm..

Regardless, a memory leak is still a memory leak. Running my program, VM size grows and grows, even though i never have more than one sound allocated at a time.
I'm getting this on several computers and other people are getting it as well ( http://basic4gl.proboards20.com/index.cgi?board=Announce&action=display&thread=1150887858
)
If for some reason you can't reproduce it, i suggest running it under the same environment (windows xp sp 2, visual express c++ sp1, audiere 1.9.4, directx 9.0c april)
I'm doing you a favor by helping you find this bug, so i need you to help me debug it by running audtest.exe and reading me your "VM Size" at each message in the program.
here's the link again http://www.cs.utah.edu/~witkowsk/files/audtest.zip
Thank you

It appears that the IDirectSoundNotify interface is not released. See
device_ds_buffer.cpp:31 and following. I made a little testcase and after calling notify->Release() memory is properly freed. Otherwise freeing it is delayed until the device is released, when DXSound releases all resources for historical reasons (which led me on a wild goose chase). I suggest making notify a member variable and releasing it in the dtor - I'll commit a fix in a little bit. Enno. -- "I would have made a good Pope." - Richard M.
