The code for DMSetDefaultSection is: 3016: PetscSectionDestroy(&dm->defaultSection); 3017: PetscSectionDestroy(&dm->defaultGlobalSection); 3018: dm->defaultSection = section; 3019: return(0); which destroys the "current" default section before setting the new one. Since my sections are passed by reference in Fortran, the only recourse I can see is to create a copy of the section before it is passed to DMSetDefaultSection. Any other ideas?

I think the bug is not that the old section is destroyed, but that the new one is not referenced.

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)?
