System: Linux bill 2.4.9 #1 Tue Aug 28 18:18:19 CEST 2001 i686 unknown
Architecture: i686

	
host: i586-pc-linux-gnu
build: i586-pc-linux-gnu
target: i586-pc-linux-gnu
configured with: ../configure --host=i586-pc-linux-gnu --prefix=/usr/linux-local/gcc-3.0.1
>Description:
libxml2-2.4.5 is not compiled correctly with -O2. Symptom: compile of
kdebase fails with 
/usr/linux-local/kde-2.2.1/bin/meinproc --check --cache index.cache.bz2 ./index.docbook
index.docbook:6: error: failed to load external entity "/kdex.dtd"]
...
where meinproc uses libxml internally

I know that gcc-3.0.x is not recommended for kde compilation. But this is
obviously a bug in gcc, since it goes away when compiled without -O2

>How-To-Repeat:
	
>Fix:
recompile without -O2 !
