Strange issue with ifx compiler and '-assume recursion'

[sblionel]

@ivanpribec

A different way to trigger this is by adding the recursive attribute to the subroutine. (Which AFAIK is the default since Fortran 2018)

You’re right that it’s the default in the 2018 standard, but Intel Fortran does not default to that unless you ask for -standard-semantics. I was very put out when I learned this.
