gcc-2.95.1 build fails on HP-UX 11 (fatal signal 11)

[Ross Campbell <campbell at hpsrv dot mantech-wva dot com>]

I am using HP's C compiler and the GNU assembler to try to build gcc-2.95.1,
version info is as follows:

  # what /usr/bin/cc
  /usr/bin/cc:
	   LINT A.11.01.00 CXREF A.11.01.00
	  HP92453-01 A.11.01.00 HP C Compiler
	   $ PATCH/11.00:PHCO_95167  Oct  1 1998 13:46:32 $
  # /usr/local/bin/as -v
  GNU assembler version 2.9.1 (hppa1.1-hp-hpux11.00), using BFD version 2.9.1

Originally, the build failed with the following error:

  (cd intl && make all)
  cc  -DIN_GCC -DHAIFA -g -DHAVE_CONFIG_H  gcov.o intl.o obstack.o alloca.o
    ../libiberty/libiberty.a -o gcov
  /usr/ccs/bin/ld: Unsatisfied symbols:
     __main (code)
  *** Error exit code 1

Determining that the newly built stage 3 compiler (xgcc) would build gcov when
the HP C compiler wouldn't, I started the make again specifying the stage 3
compiler for CC (with appropriate -B flags). This continued happily for some
time until the following error:

  /usr/local/build/gcc-2.95.1.obj/gcc/xgcc
    -B/usr/local/build/gcc-2.95.1.obj/gcc/
    -B/usr/local/hppa1.1-hp-hpux11.00/bin/
    -fgnu-runtime -c -o linking.o
    -I. -I../../../gcc-2.95.1/libobjc
    -g -DIN_GCC
    -I../../../gcc-2.95.1/libobjc/objc
    -I../../../gcc-2.95.1/libobjc/../gcc
    -I../../../gcc-2.95.1/libobjc/../gcc/config
    -I../../gcc
    -I../../../gcc-2.95.1/libobjc/../include
    ../../../gcc-2.95.1/libobjc/linking.m
  xgcc: Internal compiler error: program cc1obj got fatal signal 11
  *** Error exit code 1

Now I'm at a loss. Any suggestions? They would be welcomed.
