This is a bug report for perl from jdhedden cpan.org,
generated with the help of perlbug 1.36 running under perl
5.9.5.
------------------------------------------------------------
-----
Occasionally, when running threaded applications that use
LWP::Simple, errors such as the following occur:
Attempt to free non-existent shared string 'O_NOTRANS',
Perl
interpreter: 0x10569d98 during global destruction.
and/or
Unbalanced string table refcount: (1) for
"F_NOTIFY" during global
destruction.
The reported strings are always those for Fcntl constants,
thus leading me to suspect that there is something
non-thread-safe about Fcntl.
The attached script reproduces the problem. It must be run
a few dozen times to get an instance of the errors above.
Most of the time, however, the script fails on Abort, Seg
Fault or Hangup.
Also attached is a sample of the script's output when the
above errors occur.
