Description Jukka Holappa 2016-03-14 22:17:32 UTC 
There seems to be a memory leak that happens during every window resize event on Linux+X11 platform with libSDL 2.0.4:

==13386== 276,045 bytes in 8,365 blocks are definitely lost in loss record 95 of 96
==13386==    at 0x4C28F40: malloc (vg_replace_malloc.c:296)
==13386==    by 0x7449BB0: XGetWindowProperty (in /usr/lib64/libX11.so.6.3.0)
==13386==    by 0x4F112A7: X11_DispatchEvent (SDL_x11events.c:572)
==13386==    by 0x4F11D77: X11_PumpEvents (SDL_x11events.c:1017)
==13386==    by 0x4E85E68: SDL_PumpEvents_REAL (SDL_events.c:402)
==13386==    by 0x4E85E68: SDL_WaitEventTimeout_REAL (SDL_events.c:435)
==13386==    by 0x4E85E68: SDL_PollEvent_REAL (SDL_events.c:417)
==13386==    by 0x42588C: main (main.cpp:163)

Lost memory is quite large in above example as I tried to verify the leak by just resizing a window for a while.

The provided line numbers seem to be from SDL 2.0.3 not SDL 2.0.4.

If this memory leak is in SDL 2.0.3 then it may have been fixed with bug 2502.
Comment 2 Jukka Holappa 2016-03-15 19:54:55 UTC 
It looks like I did have some old libSDL2 library that managed to get into path before a new version I thought I was testing. I will verify that the problem is fixed in the new version but this looks like it was just my error this time.

Sorry about the noise.
Comment 3 Jukka Holappa 2016-03-15 20:13:04 UTC 
2.0.4 does not have the leak I originally reported.
