CLASS(*) access violation

MDK · ‎01-26-2010

[fortran]program crash
    
    implicit none
    
    class(*), pointer :: any => null()
    integer, target :: int = -1
    
    any => int  ! access violation (?)

end program[/fortran]

This seems to be a new problem with 11.1.054. Any attempt to do anything with a CLASS(*) variable results in an access violation. This includes fundamental activities such as assigning a pointer target (see above) or calling ALLOCATED()/ASSOCIATED() with a CLASS(*) variable. This makes it impossible to use CLASS(*) variables at all.

I can reproduce the problem you describe here. It was working in Update 2 (11.1.048) but broke in Update 3 (11.1.051). It appears that we have this fixed already for the upcoming Update 5.

A workaround is to disable Diagnostics > Check Routine Interfaces. and Diagnostics > Generate Interface Blocks.
