            Bug ID: 171162
           Summary: [JSC] Get stack pointer without pthread attr
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: utatane.tea at gmail.com

pthread_ attr operations are not safe for calling it when the thread is suspended since it can invoke malloc / free.
We would like to retrieve stack pointer without using pthread attr operations, like,

NEVER_INLINES void* getPossibleStackPointer()
{
    volatile void* stackLocation = nullptr;
    return &stackLocation;
}
