Subject: Fix 'address of fudged_set is used out of scope' code defect (sigmask)
X-Git-Tag: v8.0.0~1061
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65347c05120cc72eb8a34a67b940d817372743ae;p=platform%2Fupstream%2Flibgc.git

Fix 'address of fudged_set is used out of scope' code defect (sigmask)
(fix commit 81d04a6)

* pthread_support.c [!GC_NO_PTHREAD_SIGMASK] (pthread_sigmask): Move
fudged_set to the outer scope where REAL_FUNC(pthread_sigmask) is
called (a pointer to fudged_set could be passed to the latter function).
