[petsc-users] Question on ksp examples ex14f.F

[Danyang Su]

Hi All,

The codes can run successfully in release mode, but in debug mode, it 
causes the following error.

forrtl: severe (408): fort: (11): Subscript #1 of the array XX has value 
-665625807 which is less than the lower bound of 1

I can get rid of this error by replacing VecGetArray to VecGetArrayF90 
and do not use idx in XX. The same problem exists in ltog from 
DMDAGetGlobalIndices().

  Is there any other way to avoid this kind of error in fortran since 
the release mode can run without error? Is this caused by the 
configuration in Fortran?

Thanks and regards,

Danyang
