Runtime error with nag6.2 compiler on hobart #6

Closed ekluzek closed 6 years ago

ekluzek commented 6 years ago

This problem comes in on hobart with the nag6.2 compiler. We didn't see this with the nag6.1 compiler.

This seems to mostly be for tests with DEBUG enabled.

Here's the runtime error message for /SMS_P48x1_D_Ld5.f10_f10_musgs.I2000Clm50Cn.hobart_nag.clm-default

Thanks, @ekluzek . I agree that this looks like a legitimate problem (https://stackoverflow.com/questions/7142233/fortran-passing-same-array-as-two-dummy-arguments-to-subroutine and https://software.intel.com/en-us/blogs/2009/07/10/doctor-fortran-in-ive-come-here-for-an-argument-side-2/). I'll take a look at this.
