Perl rejects {n,m} quantifiers where n or m exceed 2147483646
(0x7FFFFFFE, the internal REG_INFTY constant). The parser was
silently accepting these, producing nodes with arbitrarily large
values that don't correspond to valid Perl regex behavior.
Add RPe_QUANTBIG error code and validate both min and max values
in the { handler before checking n > m ordering.

What
Reject
{n,m}quantifiers where n or m exceed 2147483646 (Perl's REG_INFTY).Why
Perl itself rejects these with "Quantifier in {,} bigger than 2147483646". The parser was silently accepting them, producing nodes with values that have no valid Perl semantics. This matters for tools that use the parser to validate regex patterns before compilation.
How
New
RPe_QUANTBIGerror code in Diagnostics.pm. The{handler in Handlers.pm validates both min and max values against REG_INFTY before the existing n > m check. The error message format matches Perl's native error.Testing
