The *_p.a files are used for call-profiling. What you want is jemalloc's
allocation profiling which is a different beast entirely. For this you'll 
have to re-compile jemalloc with `JEMALLOC_PROF' defined either in the
Makefile:

src/external/bsd/jemalloc/lib/Makefile.inc

or, in the defs file:

src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
