Bootstrap Failure on i686-pc-linux-gnu

Hi.

Speaking of bootstrap failures, I have one :)
I have been getting this particular error for some time now:

stage1/xgcc -Bstage1/ -B/usr/local/i686-pc-linux-gnu/bin/   -O2 -g

make[2]: *** [toplev.o] Error 1


I am trying with

env CC='gcc-3.4.2' ../gcc/configure --enable-languages=c++,c,java 
--enable-threads=posix
make bootstrap

and (if it makes any difference) in Mandrake 10

$ g++-3.4.2 -v
Reading specs from /usr/local/lib/gcc/i686-pc-linux-gnu/3.4.2/specs
Configured with: ../gcc-3.4.2/configure --enable-languages=c++,c 
--enable-threads=posix --program-suffix=-3.4.2 
--enable-version-specific-runtime-libs

I wonder if this is a bug or could there be some other reasons?
