           Summary: gcc's ia64-unwind.c makes gcc bootstrap internal error
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: bootstrap
        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 building gcc-3.3, the compiler fails when generating the stage3 level.

I reach this stage, with the following configuration, using the HP ANSI C
compiler + the GNU assembler.

env PATH=$PATH:/usr/local/bin M4=/usr/local/bin/m4 CC="cc +DD32"
/home/root/src.d/gcc-3.3/configure --prefix=/opt/gcc --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

Compilation is started with:

PATH=$PATH:/usr/local/bin gmake bootstrap-lean M4=/usr/local/bin/m4

The problem is exactly the same (same error message, at the same place) in the
following cases:

A] gcc-3.3

1) HP cc + GNU as + make bootstrap
2) HP cc + GNU as + make bootstrap-lean
3) GCC 3.2[1] + GNU as + make

B] gcc-3.2.3

1) HP cc + GNU as + make bootstrap
2) HP cc + GNU as + make bootstrap-lean
3) GCC 3.2[1] + GNU as + make
