RHBA-2010:0712 - Bug Fix Advisory

Topic

Updated perl packages that fix a bug in threading are now available.

Description

Perl is a high-level programming language commonly used for system
administration utilities and web programming.

This update fixes the following bug:

• Previously, joining a thread variable or calling the "undef" function on it in

a Perl script resulted in the following error message:

Attempt to free unreferenced scalar: SV 0x7b7dcb0, Perl interpreter: 0x7b4cfb0
during global destruction.

This error has been fixed, and using the above functions now works as expected.
(BZ#629935)

Users of threads in Perl programs are advised to upgrade to these updated
packages, which resolve this issue.
