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 = /¨\.\//;
As perl aborts\, I usually see the message: "*** glibc detected *** corrupted double-linked list: 0x08134618 ***"
gdb on the core dump reports:
