I've run Valgrind on the Linux viewer in the past, including a
few times in response to the reports of massive memory leaks (Valgrind
spotted nothing unusual - I've never been able to reproduce these leaks
or find clear commonality between the systems of the particular
residents which suffer from them).

You will likely need to run with LL_VALGRIND=x set to avoid FMOD's
SIMD detection code which fatally confuses Valgrind; this reported
problem, however, looks like something different - probably related
to SELinux.
