I can reproduce the issue after compile Emacs without optimizations.
Following is the backtrace after Emacs crash:

(gdb) run -batch -L ":../test" -l ert -l ../test/src/regex-tests.el -eval '(let (arg) (ert-run-tests-batch-and-exit arg))'

Starting program: /home/calancha/soft/emacs-master/src/bootstrap-emacs -batch -L ":../test" -l ert -l ../test/src/regex-tests.el -eval '(let (arg) (ert-run-tests-batch-and-exit arg))'
