           Summary: libobjc generation fails with internal compiler error
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: libobjc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: francois-xavier.kowalski@hp.com
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: ia64-hp-hpux11.23
  GCC host triplet: ia64-hp-hpux11.23
GCC target triplet: ia64-hp-hpux11.23

when generating gcc-3.3 on hpux-11.23, I am unable to generate the Objective-C
library.  Error message follows:

CONFIGURATION: I have used the 3 C compilers to bootstrap gcc generation. 
Whatever the starting compiler is, gcc generation fails at the stage above.  3
configuration lines are shown below:

with HP ANSI C (ansic):

env PATH=/usr/local/bin:$PATH CC="/opt/ansic/bin/cc +DD32"
/home/root/src.d/gcc-3.3/configure --prefix=/opt/gcc-3.3 --with-gnu-as
--with-as=/usr/local/bin/as --with-as=/usr/local/bin/as --without-gnu-ld
--enable-shared=yes --enable-static=yes --enable-threads=posix
--enable-version-specific-runtime-libs --enable-languages=c,c++,objc
--enable-libunwind-exceptions

with HP bundled C (ccs):

env PATH=/usr/local/bin:$PATH CC="/usr/ccs/bin/cc"
/home/root/src.d/gcc-3.3/configure --prefix=/opt/gcc-3.3 --with-gnu-as
--with-as=/usr/local/bin/as --without-gnu-ld --enable-shared=yes
--enable-static=yes --enable-threads=posix
--enable-version-specific-runtime-libs --enable-languages=c,c++,objc
--enable-libunwind-exceptions

with HP aCC (acc):

env PATH=/usr/local/bin:$PATH CC="/opt/aCC/bin/aCC -Ae"
/home/root/src.d/gcc-3.3/configure --prefix=/opt/gcc-3.3 --with-gnu-as
--with-as=/usr/local/bin/as --without-gnu-ld --enable-shared=yes
--enable-static=yes --enable-threads=posix
--enable-version-specific-runtime-libs --enable-languages=c,c++,objc
--enable-libunwind-exceptions

COMPILATION:  whatever the underlying compiler is, the compilation command used
is always:

env PATH=/usr/local/bin:$PATH /opt/OpenSource/bin/make bootstrap-lean
