Can you confirm this with MPlayer-1.0_pre5-r2?  -r3+ use custom CFLAGS (they
are masked and experimental), so I'd like to make sure that's what were dealing
with.  Just a quick look over of the code, and it's asm, something to which
I don't do well with (yes, I admit to that :), and may contact someone that
does know more.
Comment 2 Ole Tange 2004-09-24 23:51:13 UTC
I had a gut feeling that this was caused by USE=hardened. So I tried removing hardened when compiling mplayer. This gave the same result.

However, if I remove hardened and recompile first gcc then mplayer, then it works - even with 1.0_pre5-r4. I thereby feel that it is proven that it is the hardened version of gcc that conflicts with mplayer.

For my expierence with compiling older versions of mplayer, see bug 64450.
Comment 3 Chris Bainbridge (RETIRED) gentoo-dev 2005-02-01 01:22:00 UTC
I get the same thing with -fstack-protector in CFLAGS on mplayer-1.0_pre5-r5.
Comment 4 Chris White (RETIRED) gentoo-dev 2005-02-05 09:56:02 UTC
This deals with loading dll's and windows style files.  That said.. not much I can do about it, as I'd have to ask apple to fix their stuff in preventing stack smashing on linux.  Guess how that would go :P.
