Hello!

On GNU Guix, we’re seeing one 100% reproducible test failure on
i686-linux-gnu:

(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’.
