The following commit has been merged in the webkit-1.2 branch:
commit 3912a76dd6765924a85d39a22e8ff4e2b2510f9f

    Export fastMalloc, fastCalloc, fastRealloc and fastFree on GCC/Unix
    
    https://bugs.webkit.org/show_bug.cgi?id=30769
    
    When using -fvisibility=hidden to hide all internal symbols by default
    the malloc symbols will be hidden as well. For memory instrumentation
    it is needed to provide an instrumented version of these symbols and
    override the normal routines and by changing the visibility back to
    default this becomes possible.
    
    The only other solution would be to use system malloc instead of the
    TCmalloc implementation but this will not allow to analyze memory
    behavior with the default allocator.
