Description Alexandre Oliva 2001-08-02 20:39:06 UTC

I've got a collection of mpeg files that I could play with plaympeg on Red
Hat Linux 7.1, that will cause plaympeg to crash on roswell, right after it
opens the X window:
Fatal signal: Segmentation Fault (SDL Parachute Deployed)

I tried with both local and remote displays, with the same results.

The stack trace is always similar.  These are from two sample mpeg files:

#0  0x40112083 in _Hermes_X86_CPU () from /usr/lib/libSDL-1.2.so.0
#1  0x08076760 in ?? () at eval.c:41
#2  0x400f9652 in SDL_CreateYUVOverlay () from /usr/lib/libSDL-1.2.so.0
#3  0x4003b781 in MPEGvideo::SetDisplay () at eval.c:41
Cannot access memory at address 0x64

#0  0x40112083 in _Hermes_X86_CPU () from /usr/lib/libSDL-1.2.so.0
#1  0x08069bc0 in ?? () at eval.c:41
#2  0x400f9652 in SDL_CreateYUVOverlay () from /usr/lib/libSDL-1.2.so.0
#3  0x4003b781 in MPEGvideo::SetDisplay () at eval.c:41

Running Red Hat Linux 7.1's plaympeg, with the corresponding version of
SDL, works around the problem.

I can reproduce this with the Raw Hide packages, but they work(ed) fine at home:

[root@fraser root]# rpm -q smpeg SDL
smpeg-0.4.4-2
SDL-1.2.1-4

If it's likely to be relevent, the work machine (where it doesn't work) is a
PII-400 with two ATI cards, the home one a K6-III 400 with a Matrox G400.

Same problem, crashes on plaympeg (parachute deployed), using latest SDL rpm's of libSDL.org corrects it

Comment 6 lethalwp 2001-08-30 09:26:46 UTC

Tried the SDL-1.2.2-2 of rawhide, same problems it crashes
RH poeple: please change it to the normal SDL-1.2.2-1 where it works fine.

Comment 7 Bernhard Rosenkraenzer 2001-08-30 09:33:07 UTC

There is no related difference whatsoever between those files... Which 
compiler did you use to compile 1.2.2-1?

Comment 8 Bill Nottingham 2001-08-31 21:47:58 UTC

Fixed in 1.2.2-3, it appears.
