http://odamex.net/bugs/show_bug.cgi?id=1049 --- Comment #7 from Dr. Sean <grandpachuck187@xxxxxxxxx> --- After running valgrind to check for memory corruption, it appears that the data structures that store the height of moving sectors (doors, plats, etc) each frame for the rendering interpolation were not being reset properly. This means that when a map changes, these data structures would not be updated and instead of pointing to sectors for the current map, they would be pointing to random memory, causing havoc when that memory is written to. r4463 and r4464 address this issue which I believe to be the same issue causing your crashes. -- You are receiving this mail because: You are the assignee for the bug.
