[petsc-users] Question about MatGetRowMax

[Sajid Ali]

Hi Hong,

A related bugfix is that lines 2444 and 2447 from
src/mat/impls/aij/mpi/mpiaij.c in the current petsc-master are missing a
check for validity of idx. Adding a check ( if (idx)  ...) before accessing
the entries of idx might be necessary (since the docs say that the idx
argument is optional).

Thanks for the insight into the cause of this bug.
