[Dune] Fwd: RE: Memory leak, valgrind check, Dune

[Andreas Dedner]

Hi,
before a fix from Christian at the beginning of October the generic
ref.elements could leak memory (but a constant amount, which should
not increase over time). Also the copy constructor was not privat so
a code line like
GenericRefElement ref = GenericReferlements::general(type)
would work - note the missing reference &.
This was fixed in rev. 5772.
It would make life much easier if you would (at least for testing)
switch to the head revision.
To see if the SmallObjects are a problem you could remove the
inheritance from SmallObject in CachedMapping
(grid/genericgeometry/caechemapping.hh)
and in HybridMapping
(grid/genericgeometry/hybridmapping.hh)
This should at least get rid of some of the Valgrind output.
