File size: 67110 byte(s)
Fix buffer overflow for lookbehind within mutually recursive subroutines.
1 /-- This set of tests is not Perl-compatible. It checks on special features
2 of PCRE's API, error diagnostics, and the compiled code of some patterns.
3 It also checks the non-Perl syntax the PCRE supports (Python, .NET,
4 Oniguruma). Finally, there are some tests where PCRE and Perl differ,
5 either because PCRE can't be compatible, or there is a possible Perl
6 bug.
7
8 NOTE: This is a non-UTF set of tests. When UTF support is needed, use
9 test 5, and if Unicode Property Support is needed, use test 7. --/
