hello,

do you use valgrind on dolfin examples?

im on revision 4861 (dolfin0.8.8) and if i run valgrind on an example i get

priesen@vierzack01:/<8>cpp>valgrind ./demo

i can get past this even if i try to generate a suppression file from 
valgrind using -gen-suppressions / -suppressions=file.

do you get this as well?

greetings,
