Hi,

I can't reproduce either.

Is it always only with the vp? codecs?

Changed mine to match it, didn't make a difference.

Hmm, this reminds me of something:
Please try a few variantions in between debugging and not. First, 
configure MPlayer as usual without debugging.
Then open config.mak, search for "OPTFLAGS =" and replace the "-O4" in 
those flags by "-O4 -g", recompile and try if the problem persists. If 
yes, send another bugreport as you now hav proper debugging info.
Now do the same again, but instead of replacing "-O4" with "-O4 -g" 
replace it by "-O2".
Don't forget to make distclean if neccessary.
Please also post your compiler version. Have you tried with a different 
version? It _might_ be a compiler bug after all...

Looks like it should be independent from nsv, don't you think so?

Well, I did, but I'm out of ideas. The place where the crash happens has 
nothing to do with the places that are patched by the loader and looks 
rather unsuspicious.
