Hi, The 1.2.8-direct-8bit-color.patch introduced in media-libs/libsdl-1.2.8-r1 produces a segfault in most of my SDL games. I've seen this was already reported in last comment of bug #76946, but since it is closed i prefer to open a new bug. Here are some examples of the issues i've seen, that i can't reproduce with 1.2.8 or 1.2.8-r1 and the 8-bits patch reversed: lbreakout2: ------------------------------------------------------------------------------- % lbreakout2 LBreakout2 2.5.1 Copyright 2001-2003 Michael Speck Published under GNU GPL --- Looking up data in: /usr/share/games/lbreakout2 Looking up custom levels in: /home/thomas/.lgames/lbreakout2-levels /home/thomas/.lgames/lbreakout2.conf: file not found Fatal signal: Segmentation Fault (SDL Parachute Deployed) Audio finalized *** glibc detected *** double free or corruption (fasttop): 0x080c52f8 *** Abandon ------------------------------------------------------------------------------- #0 0xb7ec1999 in SDL_MapSurface () from /usr/lib/libSDL-1.2.so.0 #1 0xb7dc368e in free () from /lib/tls/libc.so.6 #2 0xb7dc3441 in free () from /lib/tls/libc.so.6 #3 0xb7fa499d in png_create_struct_2 () from /usr/lib/libpng.so.3 #4 0x080f1968 in ??

ok, i can confirm that over here ... i'll drop the patch for now and get feedback from upstream

Open a new bug, this one is specific to a version and resolved. http://www.gentoo.org/proj/en/desktop/games/#doc_chap5_sect9 Also, try to remerge both libSDL and barrage before filing the bug.
