I identified this patch or the one applied to the binutils subdirectory to cause 
regressions in the GCC/libjava testsuite on the 4.3/4.4 branches and trunk, at 
least on {x86,x86_64,powerpc}-linux:

The tests fail as:

Exception in thread "main" java.lang.NullPointerException
*** Got java.lang.NullPointerException while trying to print stack trace.

No difference, if binutils is built with 4.3.4 or 4.4.1.
