make aborts after "Segmentation Fault"

[dietrich-e dot alker at wwgsolutions dot com]

Dear Maintainers of GCC,

installing gcc-2.95.2 under Solaris 2.6 failed due to the following problem:

Both when issuing
   gmake bootstrap[-lean] (as seen in log section "gmake stage1")
and when issuing the old-fashioned sequence
   gmake
   cd gcc
   gmake stage1
   gmake CC="stage1/xgcc -Bstage1/"
gmake exits immediately after the [second(?) invocation of the] command
   ./gegenrtl tmp-genrtl.h tmp-genrtl.c
reporting
   gmake: *** [s-genrtl] Segmentation Fault (core dumped)
Thereafter, tmp-genrtl.h is empty and tmp-genrtl.c does not exist.
Note: The _first_(?) invocation of this command seems to work.

Release: gcc-core-2.95.2.tar.gz and gcc-g++-2.95.2.tar.gz (of 1999-10-25).
OS: Solaris 2.6. Mach: Sun Ultra-Sparc 5. Existing compiler: gcc 2.7.2.3.
Configured close to the instructions from the web ("Last modified 2000-3-16") in
the following way (extract of a csh script):
   set     release = 'gcc-2.95.2'
   set     objdir  = /gnu/sol26/obj/$release
   set     srcdir  = /gnu/src/$release
   if ( ! -d $objdir ) then
           mkdir $objdir
   endif
   cd      $objdir
   time    $srcdir/configure \
           --prefix=/gnu \
           --exec-prefix=/gnu/sol26 \
           --includedir=/gnu/include/$release \
           --with-local-prefix=/gnu/include/$release \
           --enable-shared \
           --enable-haifa \
           --without-fast-fixincludes \
           --enable-version-specific-runtime-libs \
           --enable-languages=c++

The last part of gmake's output (for target "bootstrap") follows here:

Any kind of advice would be highly appreciated.
