There is a bug in FreeBSD's +C<readdir_r> function that can cause a SEGV when reading large directories. +A patch is available +(see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) +and will hopefully be integrated into FreeBSD 4.6. + +=head2 $^X doesn't always contain a full path + +perl 5.8.0 sets C<$^X> where possible to a full path by asking the operating +system. On FreeBSD the full path of the perl interpreter is found by reading +the symlink F</proc/curproc/file>. There is a bug on FreeBSD, where the +result of reading this symlink is can be wrong in certain circumstances +(see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ). +In these cases perl will fall back to the old behaviour of using C's +argv[0] value for C<$^X>. + +=head1 AUTHOR + +Nicholas Clark <nick@ccl4.org>, collating wisdom supplied by Slaven Rezic +and Tim Bunce. + +Please report any errors, updates, or suggestions to F<perlbug@perl.org>. + |
