Description

Hello,our fuzzer finds that there exists stack-overflow because of recursive call of void func_body() and void parse_variable_declaration(Ident *ident, int parm) at cflow-1.7/src/parser.c.

Environment

OS: Ubuntu 20.04.1
clang version:10.0.1
Release: cflow 1.7(cflow-latest)

https://ftp.gnu.org/gnu/cflow/cflow-latest.tar.gz

Program:cflow

To reproduce the problem, we need to build cflow with asan:
CFLAGS="-fsanitize=address -g -O0" CXXFLAGS="-fsanitize=address -g -O0" \
  ./configure
  make
  make install

Command and argument

./cflow -o /dev/null poc-file

poc-file is attached below.
