Running valgrind as superuser seems to fix it, but I'm not sure why that should be necessary. {{{ $ valgrind /usr/bin/true valgrind: mmap(0x100000000, 36864) failed in UME (load_segment1). $ sudo valgrind /usr/bin/true ==38475== Memcheck, a memory error detector ==38475== Copyright (C) 2002-2010, and GNU GPL'd, by Julian Seward et al. ==38475== Using Valgrind-3.6.0 and LibVEX; rerun with -h for copyright info ==38475== Command: true }}} -- Ticket URL: <https://trac.macports.org/ticket/27559#comment:4> MacPorts <http://www.macports.org/> Ports system for Mac OS
