I tested your fix (on top of master) with my original PetIGA reproducer, and the issue seems to be fixed.

Yuck, bad bug. I pushed a one-line fix to your branch. Can you let me know if there are any outstanding issues? If it solves the problem for you, I'll cherry-pick it to 'maint'. Thanks.

In the link I have sent you, ex29 was modified to invert the order of values set. There’s also a command line that shows the error
mpiexec -n 3 ./ex29 -n 4 -invert -bs 2
I have added the correct output, but if you run with bts you’ll see some of the entries are scrambled up.

Jed,
I’m resurrecting this thread since I believe this bug has not yet been fixed. I have spent a couple of hours today tracking down a bug in my code, that I finally confined to be related with VecSetValuesBlocked.
I have pushed an example that shows the problem here https://bitbucket.org/petsc/petsc/commits/1cb7fb90b416ce1d4e4767a0d5a2ef5043... < https://bitbucket.org/petsc/petsc/commits/1cb7fb90b416ce1d4e4767a0d5a2ef5043...
Could you please have a look?
Thanks, Stefano

Do you remember about this regression? My PetIGA tests are still failing with petsc/master.
Yes, I have most of a fix in a branch that I'm working to finish.
