Hi! I’m not seeing the message below at <http://lists.gnu.org/archive/html/bug-guile-sdl/>, so resending it. (This is from <http://bugs.gnu.org/22020>.)

--- Begin Message ---Hello! On GNU Guix, we’re seeing one 100% reproducible test failure on i686-linux-gnu: --8<---------------cut here---------------start------------->8--- /gnu/store/isxqjfaglyfsbcv75y8qbqbph8v28ykr-bash-4.3.39/bin/bash: line 5: 838 Segmentation fault (core dumped) HAVE_TTF=1 HAVE_MIXER=0 sh zow ${dir}$tst FAIL: gfx.scm _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/misc/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/TTF/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/OTF/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/Type1/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/100dpi/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/75dpi/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/misc/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/TTF/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/OTF/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/Type1/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/100dpi/ _FontTransOpen: Unable to Parse address ${prefix}/share/fonts/X11/75dpi/ PASS: fading.scm ====================================== 1 of 9 tests failed (2 tests were not run) Please report to bug-guile-...@gnu.org ====================================== --8<---------------cut here---------------end--------------->8--- (Note that we run tests with the Xvfb server. See <http://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/sdl.scm#n303>.) The backtrace is mildly informative: --8<---------------cut here---------------start------------->8--- $ gdb $(type -P guile) core GNU gdb (GDB) 7.10 [...] (gdb) bt #0 0xf4d98130 in SDL_imageFilterSubByteMMX (Src1=0x5d <error: Cannot access memory at address 0x5d>, Dest=0xffb429c8 "]", SrcLength=4107944472, C=152 '\230') at SDL_imageFilter.c:2185 #1 0x09cfd470 in ?? () Backtrace stopped: previous frame inner to this frame (corrupt stack?) --8<---------------cut here---------------end--------------->8--- That SrcLength is so high suggests it might be an integer overflow. This is with SDL_image 1.2.12. To reproduce with Guix, run: guix build guile-sdl -s i686-linux --keep-failed Thanks, Ludo’.
