It is my fault that I do not read the src/Makefile of mrfioc2 carefully, mrf.munch contains almost everything, and now I load mrf.munch only, that error information is not displayed. Thanks Jeff and Andrew.

You are loading 3 separate .munch files there, and I suspect you're actually 
loading 3 separate copies of libCom and hence of the epicsThreadPrivate 
routines, thus causing the assertion you reported.  Please try modifying your 
build so that you link all your code into a single file and try loading that 
instead — in EPICS 3.13 we supported loading things separately, but in 3.14 
that is actually quite hard to do correctly, so we discourage doing it.
