AFAICS, it can't. The macro using DL_STATIC_FUNCTION_ADDRESS() are 
DL_DT_INIT_ADDRESS() which is only used in dl-init.c and 
DL_DT_FINI_ADDRESS() used in dl-fini.c and dl-close.c.
The only case where this might possibly be reentered would be parallel 
calls of dlopen()/dlclose(). I'm not even sure those calls are supposed 
to be thread safe.
