const char * with a string inside its buffer, it released the buffer before copying the string. - Added a new FString constructor that creates the string from a lump. - Fixed: G_DoReborn() calls G_InitNew() with mapname set to level.mapname. G_InitNew() then copies it onto level.mapname, which is undefined behavior (although it does work as we want it to). - Modified FMemLump to store its data using FString. That class provides a convenient method of storing reference counted data, so now FMemLump doesn't need to muck about sneakily using const_casts and possibly tricking its users into thinking that an old one is still valid after being assigned to a new one. - Fixed: The IMGZ, PNG, PCX, and JPEG loaders assumed the files were large enough for their headers without actually checking.
