I'm trying to update mplayer. I'm getting the error below. I have also tried with gcc 3.3 and with USE="-*", same result.

Reproducible: Always
Steps to Reproduce:
1. emerge -u mplayer
2.
3.

Actual Results:

[Comment 1 Luca Barbato 2005-02-21 17:19:35 UTC]

dump -fforce-addr -g

[Comment 2 Helge Haugland 2005-02-21 17:52:31 UTC]

Tried 
CFLAGS="-march=athlon-xp -pipe -fomit-frame-pointer" emerge -u mplayer

Same result :(

[Comment 3 Luca Barbato 2005-02-22 05:42:20 UTC]

try adding -O2

[Comment 4 Helge Haugland 2005-02-22 08:08:03 UTC]

CFLAGS="-march=athlon-xp -pipe -fomit-frame-pointer -O2" emerge -u mplayer
worked!
Perhaps even more CFLAGS flitering is needed?

[Comment 5 Luca Barbato 2005-02-22 08:22:44 UTC]

at least -O1 is required to have gcc produce a working code. Known issue

[Comment 6 Helge Haugland 2005-02-22 09:30:40 UTC]

Then the ebuild should ensure that at least -O1 is used when compiling

[Comment 7 Luca Barbato 2005-02-22 10:28:39 UTC]

EVERY code produced by gcc-3.xx
