SUMMARY: AddressSanitizer: stack-overflow /root/fuzzing_pcre2/pcre2-10.42/src/pcre2_dfa_match.c:533 in internal_dfa_match
==1218==ABORTING

“
On my computer, it will stack overflow after about 7800 recursive calls.

This is not a bug; it's just that the default recursion limit is very large. Please check the documentation for pcre2_set_depth_limit(). This is part of what it says: ",,, is supported by pcre2_dfa_match(), which uses it to limit the depth of nested internal recursive function calls that implement atomic groups, lookaround assertions, and pattern recursions. This limits, indirectly, the amount of system stack that is used. It was more useful in versions before 10.32, when stack memory was used for local workspace vectors for recursive function calls. From version 10.32, only local variables are allocated on the stack and as each call uses only a few hundred bytes, even a small stack can support quite a lot of recursion."
