[Valgrind-users] [Helgrind] Segfault -> mallocSanityCheckArena

[<gt...@ma...>]

I get the below error when trying to use Helgrind on VTK based applicatio=
ns
(www.vtk.org).  When the sanity-level is at the default, Valgrind seg-fau=
lts
without any warning or other output.  This happens very early in the exec=
ution
of the program.

$ valgrind --skin=3Dhelgrind --sanity-level=3D5 ./ParaView

When run using the Memcheck skin, the program runs fine.  The first error
reported (which appears to later in the programs execuation) is:
