            Bug ID: 165075
           Summary: WTFLogVerbose is passing arguments to WTFLog
                    incorrectly
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ivlev.igor at gmail.com

WTFLogVerbose is a variadic function.
It is trying to pass argument list to another variadic function, WTFLog.
*This is not possible* (leads to output corruption), we may consider using a variadic macro or a function that takes va_args instead.
Explanation why this is not possible:
