Core generated on bootstrap for i386-sequent-sysv4

[Frederic Marie]

Hello,

I experienced the following fatal error while compiling
gcc 2.95.2 on Sequent Numa machines (i386-sequent-sysv4):

stage2/xgcc -Bstage2/ -B/usr/local/i386-sequent-sysv4/bin/  -DIN_GCC     -O2 -g -O2  -DHAVE_CONFIG_H  -o genpeep \
 genpeep.o rtl.o bitmap.o print-rtl.o ` case "obstack.o" in ?*) echo obstack.o ;; esac ` ` case "alloca.o" in ?*) echo
alloca.o ;; esac ` ` case "" in ?*) echo  ;; esac `  ` case "" in ?*) echo  ;; esac ` ` case "" in ?*) echo  ;; esac `
./genpeep ../../gcc/config/i386/i386.md > tmp-peep.c
/bin/sh: 26318 Memory fault - core dumped
make[2]: *** [s-peep] Error 139

make[1]: *** [bootstrap] Error 2
make[1]: Leaving directory `/sita/GNU/gcc-2.95.2/OBJDIR/gcc'
make: *** [bootstrap] Error 2

I am able to reproduce it manually:
genpeep ../../gcc/config/i386/i386.md > tmp-peep.c
Memory fault(coredump)

The core:
gdb -core core genpeep

I will be more than happy to provide any necessary additional
information.
