Prevent double free for too big repetition quantifiers (#13332)
Prevent double free for too big repetition quantifiers
The previous implementation calls `free(node)` twice (on parsing and compiling a
regexp) when it has an error, so it leads to a double-free issue. This
commit enforces `free(node)` once by introducing a temporal pointer to hold
parsing nodes.
