Title: Memory leaks when upgrading to 2.4.0 from 2.3.2
Post by: Pinkii on August 20, 2016, 11:36:14 am

Have anyone had memory leaks when upgrading from 2.3.2 to 2.4.0?

Didnt have at that moment.

I have tried the sfml pong example https://github.com/SFML/SFML/tree/master/examples/pong (https://github.com/SFML/SFML/tree/master/examples/pong) and the result of valgrind:

==4716== LEAK SUMMARY:
==4716==    definitely lost: 578,736 bytes in 19 blocks
==4716==    indirectly lost: 0 bytes in 0 blocks
==4716==      possibly lost: 42,878,414 bytes in 7,325 blocks
==4716==    still reachable: 155,291 bytes in 785 blocks
==4716==         suppressed: 0 bytes in 0 blocks
 

I was just asking if anyone had the same problem or was that I'm derp or something.

Tried and didnt fix it. The pong still has memory leaks.

I have tried to compile the sfml with the -g flag, but it doesn't show the line of the trace.

The leak we can fix was fixed in the PR I submitted. On my system, valgrind reports 0 bytes lost after applying the patch. The remaining bytes (there are less with the patch than without) you are seeing is coming from somewhere inside the Intel graphics driver. This has been an issue for a very long time. There is nothing we can do about it.

Oki. Thanks for your effort and time!

I will look if I have any driver than is not updated.

Thanks!
