The following simplified source code creates an "Internal compiler error" when compiled with /64 and /check

Subroutine DRGD2Z (PSZL)
Character(len=*) :: PSZL(*)
Character(Len=10), External :: DRUTBQ
PSZL(1)(52:61) = DRUTBQ(1)
END

Without /64 no error appears.

The error can be avoided with an additional assignmnet:

Subroutine DRGD2Z (PSZL)
Character(len=*) :: PSZL(*)
Character(Len=10), External :: DRUTBQ
Character(Len=10) :: xxx
xxx = DRUTBQ(1)
PSZL(1)(52:61) = xxx
END

Thomas

Thank you for this bug report. I have made a note that it needs fixing.

This failure has now been fixed for the next release of FTN95.

Does Subroutine DRGD2Z (PSZL) need an interface for using PSZL ?
Character(len=*) :: PSZL(*)

Perhaps (len=*) is always provided, so PSZL(*) is an array of unknown size.
So, len(PSZL(1)) is available, but size(PSZL) is not.

I would be interested if the following works.
Code:
  Subroutine DRGD2Z (PSZL)
  Character(len=*) :: PSZL(*)
  Character(Len=10), External :: DRUTBQ
  if (len(PSZL(1)) >= 61) then
    PSZL(1)(52:61) = DRUTBQ(1)
  else
    write (*,*) 'len(PSZL) =',len(PSZL(1)),' too small'
  end if
  END

The original code provided by Thomas compiles in 32 bits and in 64 bits without /CHECK so FTN95 can be used to investigate any limitations.
