When compiling gcc 1.37.1 I'm getting a core drop as well.  The system
is a Data General AViiON (88000)

The culprit in this case is gnulib as well.

  _bdiv _cmpdi2 _ucmpdi2 _fixunsdfdi _fixdfdi _floatdidf _varargs; \
        do \
          echo    .
        do \
          echo ${name}; \
          ./gcc -B./ -fstrength-reduce -O -I. -I. -I./config  -c -DL${name} ./gn

          ar rc gnulib ${name}.o; \
          rm -f ${name}.o; \
        done
