On perl-5.8.8 I see empty elements for index 127-131.
On perl-5.8.9-tobe, perl-5.10.0 and perl-blead I see no empty elements.
If I add: use strict in the code then I do get *** glibc detected ***
double free or corruption (!prev): 0x08135f00 *** with 5.8.8. (5.8.9-
tobe works fine)
Also: the /o modifier in your regexes does nothing.
(It is best never to use /o.)
If I use:
my @ignore_list = (
qr/ all milters$/, # 0
...
qr/^write to [a-fA-F\d]{8}/, # 126
);
push @ignore_list, (
qr/^xsasl_cyrus_server_/, # 127
...
qr/socket: wanted attribute: /, # 131
);
Then I do get the expected output.
Can you try this work around and confirm that the error goes away?
Kind regards,
Bram
