Fixed bug 5339 - Minor memory leak in SDL_x11events.c

wcodelyokoyt

The atom name that X11_GetAtomName() returns never gets freed, which result in a minor memory leak (14 bytes?) every time the user drops a file on a window.
You can see the line in question here:
https://github.com/spurious/SDL-mirror/blob/6b6170caf69b4189c9a9d14fca96e97f09bbcc41/src/video/x11/SDL_x11events.c#L1350

Fix: call XFree on name after the while loop.
