Segfault parsege_calc after build on Ubuntu 18.04 64bits

[mingodad]

After clone and build this project on Ubuntu 18.04 64bits with g++-9 and clang-16 and trying to execute parsegen_calc I'm getting a segfault:

./parsegen-calc
parsegen-calc: parsegen-cpp/src/parsegen_shift_reduce_tables.cpp:28: void parsegen::add_terminal_action(parsegen::shift_reduce_tables&, int, int, parsegen::action): Assertion `at(p.terminal_table, state, terminal).kind == action::kind::none' failed.
Aborted (core dumped)

with valgrind:
