Can you recommend any particular approach to this problem? > What we do in gstreamer for it is to use g_try_malloc when doing allocations where the size is based on input data. There might be places where this is not done. Also objects are allocated using g_slice and would terminate the app if you run out of memory. If you get termination on low memory, it would be a good idea to check the backtrace and file a bug if the code is using g_malloc for data.
