I'm using 3.7.4 and still get SEGV in pdgssvx routine. Everything works
fine
with 3.5.4.
Do I still have to stick to maint branch, and what are the chances for
these
fixes to be included in 3.7.5?
3.7.4. is off maint branch [as of a week ago]. So if you are seeing
issues with it - its best to debug and figure out the cause.
This bug is indeed inside of superlu_dist, and we started having this issue
from PETSc-3.6.x. I think superlu_dist developers should have fixed this
bug. We forgot to update superlu_dist?? This is not a thing users could
debug and fix.
I have many people in INL suffering from this issue, and they have to stay
with PETSc-3.5.4 to use superlu_dist.
To verify if the bug is fixed in latest superlu_dist - you can try
[assuming you have git - either from petsc-3.7/maint/master]:
--download-superlu_dist --download-superlu_dist-commit=origin/maint

Hi Satish,
I did this:
git clone -b maint https://bitbucket.org/petsc/petsc.git petsc
--download-superlu_dist
--download-superlu_dist-commit=origin/maint (not sure this is needed,
since I'm already in maint)
The problem is still there.
Cheers,
Anton
