[Bug c/40064] New: gcc-4.4.0 fails to compile svn trunk mplayer.


Opened: 2009-05-07 16:49 CEST

I reported this with mplayer's bugzilla
(http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1461)
and was told:

These are gcc bugs, more so if it worked with previous gcc versions.  Go report
bugs to the gcc team.

-------------------------------------------------------------------------------------------------------------
So here it is:

I built gcc using default CFLAGS etc and
I configured mplayer with --enable-gui and default CFLAGS. 

The build dies with:

/usr/bin/gcc -Wundef -Wdisabled-optimization -Wno-pointer-sign
-Wdeclaration-after-statement -std=gnu99 -Wall -Wno-switch -Wpointer-arith
-Wredundant-decls -O4 -march=native -mtune=native -pipe -ffast-math
-fomit-frame-pointer -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
