We have a code that has behaved quite well with earlier Intel compilers (17.x.x) and other Fortran compilers (including NAG's own), but gets a segfault when 18.0.0 is used. The code is used under licence from 3rd party and cannot be posted on open forum. It will take a significant amount of effort to cut it down to a minimum exhibitor. Could you advice on how to proceed please?
