EM64T (8.1.019) character len question

[ipattielgc]

Anyone hve any idea why the len intrinsic below is returning zero instead of 3 billion for this EM64T app? Setting local ints to 8 bytes via /4I8 does not seem to help. I'm trying to determine if the hidden length argument passed with characters are kind=4 or 8 on EM64T. I've looked in the docs plenty, but am notquite sure if rules about such things apply equally to IA64 and EM64T.

System is Windows XP x64 release version, AMD 64, SDK 3790.

Thanks in advance, Ian.

program main

integer(int_ptr_kind()), parameter :: nclen=3000000000

character(len=nclen) :: cmsg
print*,len(cmsg,8),nclen

stop
end

d: tengine>ifort /4I8 hello.f90

Looks like a bug - please report it. When you do, please reference T55818.

Submitted. But, would you know if the hidden character length passed by value followinga character variable address usingthe em64T compiler in a call like:

call sub( cvar )

is int_ptr_kind() or integer(4) ? I looked at some assembler, and I think its int_ptr_kind() same as the address, regardless of the compile integer setting.

The docs say IA64 is integer(8), so em64t is?

Thanks, Ian

It is 8 bytes on EM64T, same as Itanium.
