--- Comment #8 from vehre at gcc dot gnu.org --- Hi Steve, you asked what other compilers have to say to the code (the one in the description). Ifort: > ifort bug.f90 -o bug -coarray bug.f90: catastrophic error: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error. compilation aborted for bug.f90 (code 1) > ifort -v ifort version 15.0.1 While Cray say: >ftn bug.f90 -o bug >ftn -V Cray Fortran : Version 8.5.1 Wed Nov 02, 2016 05:35:28 I can't run the resulting executable though, because some runtime library is reported missing (I don't get how to setup it up correctly). Changing the program to subroutine has no effect. - Andre
