[petsc-dev] DMSetDefaultSection destroys old sections

[Chris Eldred]

I am using DMSetDefaultSection and DMCreateLocalVector to create
vectors in my code, but errors are occurring because
DMSetDefaultSection destroys old sections. My usage pattern is

for each variable
call DMSetDefaultSection
call DMCreateLocalVector

which fails if there is more than one 1 variable that uses the same
section since the sections are being destroyed when a new one is set.
Is there a reason for this behavior in DMSetDefaultSection (ie can a
version of DMSetDefaultSection that does not destroy the old sections
be provided)?
