--- Comment #4 from smateo <sergi.mateo at bsc dot es> --- Hi Jerry, This code is a simplification of a code that our tool generates to support a tasking programming model. I know that I don't need a derived type to call a C function. If I recall correctly, I needed to reproduce this problem. Of course using the ISO_C_BINDINGS interoperability module and BIND(C) would be a more appropriate way of doing it, but they were introduced in F2003. I guess that a code like the one I attached should work in the pre-interoperability era (we may need to remove the VALUE attributes since this attribute was introduced also in F2003). I decided to open this ticket because, as you said, this code works nicely in x86_64 (I also tried in some ARM machines and also worked), and because changing the optimization level flags made it work. I also tried to compile this code with XLF and works nicely. Best regards, Sergi
