Subject: Fix uninitialized cache when pthreads are used
X-Git-Tag: 1.0_branch~592
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=634ba33b5b1fcfd5a0e7910f9991b4ed4f674549;p=profile%2Fivi%2Fpixman.git

Fix uninitialized cache when pthreads are used

The thread local cache is allocated with malloc(), but we rely on it
being initialized to zero, so allocate it with calloc() instead.
