Valgrind

Typical OSX invocation

valgrind --leak-check=yes --dsymutil=yes --track-origins=yes ./unittests_hemelb

When using Valgrind to debug HemeLB, there can be noise due to issue https://bugs.kde.org/show_bug.cgi?id=196528 -- the suppression added in that bug report only works for Leopard, now Snow Leopard, sadly. The following generated suppression can be added to your local valgrind suppresions file:

{
   snow_leopard_pthread_rwlock_fix
   Memcheck:Cond
   fun:pthread_rwlock_init
}

There is also an OpenMPI suppressions file which is supplied with openmpi: use

--suppressions=/opt/local/share/openmpi/openmpi-valgrind.supp
