This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.7.
-----------------------------------------------------------------
[Please enter your report here]
This script (three lines, below) caused perl to fault, apparently during a
memory
allocation operation.
The first character in the re is U+00a8.
#!/usr/local/bin/perl -w
use encoding 'utf8';
my $x = /ยจ\.\//;
As perl aborts, I usually see the message:
"*** glibc detected *** corrupted double-linked list: 0x08134618 ***"
gdb on the core dump reports:
