Fedora xen - May 2009 - Problems rebuilding fedora xen-3.3.1-11.fc11.src.rpm with debug enabled

Hello.

I''m trying to rebuild xen-3.3.1-11.fc11.src.rpm with debug enabled to
be
able to get more debug information from pv_ops dom0 kernels.

.. and I have a problem. Has someone else seen this problem? 

I modified xen.spec and added "debug=y verbose=y crash_debug=y"
options to
"%if %{hv_build}" section to make command.

Running "rpmbuild -bb xen.spec" gives this error:

traps.c: Assembler messages:
traps.c:1343: Error: bad register name `%sil''
make[4]: *** [traps.o] Error 1
make[4]: Leaving directory
`/root/rpmbuild/BUILD/xen-3.3.1/xen/arch/x86''

Based on some googling it could be a gcc problem? I''m running:

# rpm -qa|grep gcc
gcc-gfortran-4.4.0-3.i586
libgcc-4.4.0-3.i586
gcc-c++-4.4.0-3.i586
gcc-debuginfo-4.3.2-7.i386
gcc-4.4.0-3.i586

OK it''s a Xen bug. Patch from the above mail should fix the problem.
