Detailed Description

std::regex_error-compatible exception.

Thrown on two paths, both preserving the std::regex_error contract:

Invalid for both backends (a syntax error): real rejects, and so does std — the exact std .code() is preserved and what() keeps std's message, so a syntax error is byte-for-byte std.
Strict-policy rejection (policy): a pattern real cannot represent linearly but std could (a backreference, an unbounded lookaround, a POSIX class) — code() is error_complexity and what() carries a REAL-identifiable message. Under policy::fallback this path delegates to std instead of throwing, so the only thrown case there is the invalid-for-both one above.
