Thanks for the report.

An internal compiler error is by definition a compiler bug and it is probably worth reporting this to Intel. From memory I think ifort has fallen over on this file before (but this was 10 or 11 point something and I thought it had all been fixed) so it's probably worth reviewing the FoX-discuss archives. I think the most recent post is this one: https://groups.google.com/forum/?hl=en#!topic/fox-discuss/FTUc5Ro9nxI but also see this one: https://groups.google.com/forum/?hl=en#!topic/fox-discuss/aWegvAKe4vo and links from there. It may be worth raising this on that list too as others may have found a work around.

I'm seeing the same ICE with gfortran-7.3.1 (and FoX 4.0.3):

gfortran -c fox_m_fsys_format.F90
fox_m_fsys_format.F90:1289:0:

     if (.not.checkFmt(fmt)) then
 
internal compiler error: Segmentation fault

This is a compiler bug, not a problem with FoX, but I've not seen this with gfortran before. For what it's worth, the tests on travis are passing, but they use gfortran-4.9. It's probably worth configuring something newer too.

Also - see #57 for a possible work around
