Re: PostgreSQL 12 crash with segmentation violation in heap_freetuple

in current 12 branch I get

make[2]: Verzeichnis „/opt/postgresql/src/backend/parser“ wird betreten
'/usr/bin/perl' ./check_keywords.pl gram.y
../../../src/include/parser/kwlist.h
/usr/bin/bison -Wno-deprecated  -d -o gram.c gram.y
/usr/bin/bison: invalid option -- 'W'
Usage: /usr/bin/bison [-dltvyVu] [-b file-prefix] [-p name-prefix]

Thank you
Marcel
