Freeze in regex parser

[e5l]

Failed to match the following regex:
(([a-z]|\d|[\Q+-.\E])+)\Q://\E((([a-z]|[A-Z]|\d|[\Q$-_.+\E]|[\Q!*'(),\E]|(\Q%\E(\d|[A-F]|[a-f])(\d|[A-F]|[a-f]))|[\Q;?&=\E])+)(\Q:\E(([a-z]|[A-Z]|\d|[\Q$-_.+\E]|[\Q!*'(),\E]|(\Q%\E(\d|[A-F]|[a-f])(\d|[A-F]|[a-f]))|[\Q;?&=\E])+))?\Q@\E)?(((([a-z]|[A-Z]|\d|(([a-z]|[A-Z]|\d)([a-z]|[A-Z]|\d|\Q-\E)*([a-z]|[A-Z]|\d)))\Q.\E)*([a-z]|[A-Z]|(([a-z]|[A-Z])([a-z]|[A-Z]|\d|\Q-\E)*([a-z]|[A-Z]|\d))))|(\d+\Q.\E\d+\Q.\E\d+\Q.\E\d+))(\Q:\E(\d+))?(((\Q/\E([a-z]|[A-Z]|\d|[\Q$-_.+\E]|[\Q!*'(),\E]|(\Q%\E(\d|[A-F]|[a-f])(\d|[A-F]|[a-f]))|[\Q;&=\E])*)+)(\Q?\E(([a-z]|[A-Z]|\d|[\Q$-_.+\E]|[\Q!*'(),\E]|(\Q%\E(\d|[A-F]|[a-f])(\d|[A-F]|[a-f]))|[\Q;&=\E])*))?(\Q#\E(([a-z]|[A-Z]|\d|[\Q$-_.+\E]|[\Q!*'(),\E]|(\Q%\E(\d|[A-F]|[a-f])(\d|[A-F]|[a-f]))|[\Q;&=\E])*?))?)?
