Description Evgeny Kapun 2017-09-28 14:26:25 UTC 
Commit 52dcef74bdc5 [1], which was a fix for bug #3790, introduced a new bug: now, calling SDL_FreeSurface(surface) deallocates surface->map even if there are other references to the surface. This is bad, because some functions (such as SDL_ConvertSurface) assume that surface->map is not NULL.
