Hi,

is this happening on a x86 32 bits machine? This issue was pointed out already 
by Ovidu Sas: <http://lists.sip-router.org/pipermail/sr-dev/2016-January/thread.html#32757>,
but I had no 32 bits machine to test this on, and also no idea why it does not
work (I see no error message on my 64 bits Debian Jessie).

All I see is that we are assigning a
    void* (*)(tlsf_t, size_t)
to a
    void* (*)(void* , unsigned long)
yet tlsf_t is defined as `typedef void* tlsf_t`, and size_t and unsigned long 
have the same width on this architecture...

Do compiling with clang generates an error too? If yes, is the error message
more specific about the issue?

Any other idea?
