Don't be so lame.  Show us the contents of relevant memory!
In this case, the words at 0x380AC1A8 and at 0x4000960, and
preferably a couple words on either side of both addresses, too.

0x380AC1A8 ought to be inside one of the pieces of valgrind or memcheck.
Such a piece is statically linked at 0x38000000; for example see
     valt_load_address_pri_norml="0x38000000"
     VALT_LOAD_ADDRESS_PRI = 0x38000000
and similar in the source tree (configure, Makefile, etc.) for valgrind.
Also see:
     readelf --headers $prefix/lib/valgrind/memcheck-<arch>-<os>
