Possible Coarray bug

[luke_m_]

I am having problems with a Coarray fortran code.

I have managed to isolate one of the issues in the form of the attached code and output. It executes correctly using the Cray compiler but it gives a divide by zero in the prolog of the subroutine using Intel compilers. I have tried with both versions 14 and 15 of the compiler with the same result.

Compile line is

ifort -coarray -switch no_launch -o error-caf-intel error-caf.f90

Execute line is

mpiexec.hydra -np 4 error-caf-intel

Please let me know if you would like any further information.

Looks like an ifort defect.  I've reported this to the developers, tracking ID DPD200362909.  I'll keep this thread updated with news.

This issue is now fixed in a future version of the compiler.

This issue is now targeted to be fixed in the 15.0 compiler.

I’m confused, isn’t the 15.0 compiler already out? Did you mean to say the update coming early next year?

Right, the fix is targeted for 15.0.2 (update #2).
