Hi, 

I have run msan checks (compiled with -g -fsanitize=memory , I am using Clang14 with -Os) and I have got the following Warning:

    #10 0x1c9699e in axi::tlm_phase_BEGIN_PARTIAL_REQ::tlm_phase_BEGIN_PARTIAL_REQ()


First line, where it starts to complain is

DECLARE_EXTENDED_PHASE(BEGIN_PARTIAL_REQ);
DECLARE_EXTENDED_PHASE(END_PARTIAL_REQ);
DECLARE_EXTENDED_PHASE(BEGIN_PARTIAL_RESP);
DECLARE_EXTENDED_PHASE(END_PARTIAL_RESP);
DECLARE_EXTENDED_PHASE(ACK);


Is this a know issue with SystemC macro DECLARE_EXTENDED_PHASE, or something else?
Any suggestion how I can disable the warning in this particular case?


Thanks
