Best to do what Rico says, but.... If the tcmalloc library is dynamically linked to Moses, running ldd will show it is linked into moses: #ldd bin/moses ..... libtcmalloc_minimal.so.4 => /usr/lib/libtcmalloc_minimal.so.4 (0x00007ff49f5a2000) ... You can force it to statically link by deleting rm /usr/lib/libtcmalloc*.a
