ICE during linking for coarray code

Hi,

I've just install the last version of the compiler, ifort version 15.0.0, on the following kernel 3.15.10-200.fc20.x86_64.

This version fails to compile a (rather large) code with the "-O2 -ipo" options .

Actually, the compilation step goes ok but the problem appears during the linking step.

Here are the warning/errors:

Compiling the same code, with the same compilation options, but using ifort version 14.0.3 gives these warnings but no internal compiler error:

From the set of warning, I guess I got something wrong with my MPI installation, but I'm wondering why everything is ok for the 14 version but not for the 15 one.

Thanks for your feedback.
