            Bug ID: 172595
           Summary: Clang warns about (intended) returning pointer to
                    stack location in WTF/wtf/ThreadingPthreads.cpp
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aperez at igalia.com

When building with Clang (at least on GNU/Linux), the warning is:

  ../../Source/WTF/wtf/ThreadingPthreads.cpp:105:13: warning: address of stack memory associated with local variable 'stackLocation' returned [-Wreturn-stack-address]
      return &stackLocation;                                                                                                                             
              ^~~~~~~~~~~~~                                              
  1 warning generated.        

It is possible to use a #pragma to silence this warning (as done
for GCC). I'm making a patch to silence this warning, because in
here returning a pointer to the stack is precisely what's intended.
