[ID 20010811.006] re_eval: logical leaks
Message ID:
200108101734.f7AHYrJ17647@crypt.compulink.co.uk
This is a bug report for perl from hv@crypt0.demon.co.uk
generated with the help of perlbug 1.33 running under perl v5.6.1.
-----------------------------------------------------------------
[Please enter your report here]
perl -Dr -we '"ab" =~ /^(a(??{"(?!)"})|a(?{1}))b/'
suggests that 'logical' is not correctly restored on backtracking.
Still fails at 5.7.2.
