Hello, Linphone developers!


I am the new to the list.

I did not find the message regarding the memory leak of the new windows version of the linphone.


During the evaluation and interop checkings with Linphone Windows version 3.7.0 we faced the problem of serios memory leaks.

When 1 run g.722 and H.264 CIF call, I found using process explorer I found that

1) the leak is about 16KB/sec during the call

2) significant leaks between calls


I found the program DrMemory that can perform profiling for programs compiled without MS VisualStudio.

All report I placed on here:


Please see the results.txt leaks are from error #254. There are number of memory leaks there.


The most important repeatable memory leak is


LEAK 480 direct bytes 0x04f963a0-0x04f96580 + 16 indirect bytes

Error #309:

Error #310:

Error #312:

Error #315:

If you are familiar with the linphone project please assist to fix it


Thanks in advance
