Derek How are you interfacing it with Julia?
It could be there is an error in the way you are interfacing it. This error could be undetected with gfortran, but be visible with ifort. The error message sounds as if you are writing to a memory location that should not be written to (e.g. to a constant or a string). It is easy to get confused with what is a pointer and what not when using Julia's `ccall` for Fortran code, and this can lead to that kind of error. If you point to your code, people might be able to give better advice. -erik On Fri, May 6, 2016 at 6:03 PM, Derek Tucker <de...@tetonedge.net> wrote: > I have an external library that I am interfacing with julia, when I > compile it with gfortran it runs without a problem.
