gawk-3.1.2-alt1 crashes where gawk-3.1.1-alt4 worked (hinders  emacs compilation; that\'s how it was discovered)

At the same time the old gawk works:

for (( i = 0; i < 10; ++i )); do emacs -q -batch -f list-load-path-shadows; done  2>&1 | /user/imz/bin/gawk-3.1.1-alt4 \'/!! /{ r++; } END{ if (r) printf \"There were %d errors while recompiling Emacs Lisp modules.\\n\", r; exit r; } /.*/\'
