Sorry, but the correct pattern is: L"(FILE_TYPE.*?)\\s*{\\s*PRIO\\s*=>\\s*(\\d+).*?"

To be precisely it doesn't crash, it just generates an exception when parsing: '{' character. Perl handles this correctly, here - it has to be escaped in order to work correctly...

Resolution: → fixed
Status: new → closed

(In [84371]) When a {} repeat sequence is invalid or incomplete, and the language is Perl, then backtrack and treat the sequence as a literal, not a repeat operator. Fixes #8569.
