Hi, this patch fixes the last failed fortran test case on arm-linux-gnueabihf: select_type_4.f90, which did always fail at -O2 and above.
It was caused by a strict aliasing violation, when passing a value of the type
"class(x),pointer" to a formal procedure parameter of the type
"class(x),target".
The patch resolves this, by creating a temporary value of type "class(x),target"
which can be passed to the procedure without violating the strict aliasing
rules.
Boot-strapped and regression-tested without any regressions
on x86_64-unknown-linux-gnu and arm-linux-gnueabihf.
OK for trunk?
Thanks
Bernd.
