Subject: Fix memory leak in the pthreads thread local storage code
X-Git-Tag: 1.0_branch~560
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5c935473d8a193b3510f8605a6658ea6ac998fd1;p=profile%2Fivi%2Fpixman.git

Fix memory leak in the pthreads thread local storage code

When a thread exits, we leak whatever is stored in thread local
variables, so install a destructor to free it.
