build failure on with gcc 4.3 & core2

[bjrtchsupp@…]

I've been having an issue compiling mplayer using a recent version of gcc 4.3 (compiled locally approx 24-48 hours ago from the svn around 28-Feb-2007). I get this error when it gets to the libavcodec section of the compile. this compile is VERY stripped out (I havent loaded any additional libraries such as xvid, x264 or anything else). This is a vanilla build from the svn (mplayer @ v22428, ffmpeg sections @ 8211). I have tested the compile and it is successful when using march/mtune to be anything reasonable (I tried leaving it out completely as well as prescott and pentium4(m)). I also have tested using -O0 thru -O4 and the only difference is the amount of times it tells me that error (more errors as the # increases).

Below I have included 4 outputs. The first is the one that the configure script generates (-O4 & core2). The second is after I altered it to be -O0. The third is -O4 & prescott. The fourth is just -O4 with no march/mtune. These changes were made only in config.mak in the root directory

I was able to previously build mplayer with no problems when it was at version 22189 when I was using gcc 4.3 built from a snapshot from 04-Dec-2006. Now after this update I am no longer able to compile. I also no longer have the old gcc build to test the current version of mplayer against.

This looks similar (virtually identical, same exact error) to a bug I found on the gcc buglist submitted by one of the ffmpeg developers back in Oct06. You can reference it @ ​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29440

Please let me know if you want any additional outputs/tests run. I wasn't sure if this was a mplayer or ffmpeg bug but since it crashed when building mplayer I put it here just in case it was an issue with something else mplayer did in its configure or something related. I apologize if I should have posted this under ffmpeg.
