Re^3: 5.10.0 regex slowdown

It would neat to see the re=debug dump of your pattern, piped into grep TRIE to see whats going on. I suspect that you can do it easiest with perl -c on code with a use re 'debug'.

perl -c -Mre=debug SCRIPT 2>&1 | grep TRIE

Should do it.

Actually if you could grep for JUMP and JMP too it would be good.

With `-c -Mre=debug`, I get no output other than `668954.p10 syntax OK`, but as the regex is built at runtime, I wouldn't expect to? Running the code on the non-pathological case with `use re 'debug';` I get 2 million lines of log of which 11,282 contain 'TRIE'; and the are no 'JUMP's or 'JMP's. The pathological case is running (and has already reached 10 million+ lines), but it looks like it is going to take quite a while. Can you /msg me your email and we can take this off line.
