** Summary changed:

- does not work when called from a program compiled with ifort
+ MUMPS does not work when called from a program compiled with ifort

[Bug 680413] [NEW] does not work when called from a program compiled with ifort

[Rodrigo Valiña Gutiérrez]

Public bug reported:

when I compiled with ifort the example program provided with MUMPS
source code, linking to the MUMPS in the system, and when I execute it,
I get an error, also, solution should be 1 2 3 4 5.

I am not sure whether a program compiled with ifort should be able to
use libraries compiled with gfortran, as MUMPS is.

- compiling with ifort 12
