Can't this be a PGV annotation?

Additional Description:
In
TrieLookupTablethe default destructor will use call-stack to recursively find all unique_ptr and reset them. If the string added to Trie is very long, for example, with 40000 characters, the Trie will have a depth of 40000 and call-stack will encounter stack-overflow.Added a constraint length<=1000 for route.prefix().size().
Risk Level: low
Passed a crashed test case reported by network_readfilter_fuzz_test.
