Internal Compiler Error in gfortran 14.1.0 #155

Open ATPXenogen opened 1 month ago

ATPXenogen commented 1 month ago

Solution to issue cannot be found in the documentation.

Issue

This is a minimal reproducible example

subroutine icemaker()
  implicit none
  real(kind=8) :: re
  re = func(1d0)%re
  contains
  complex(kind=8) function func(x)
    real(kind=8) :: x
    func = x
  end function
end subroutine icemaker

When compiled with gfortran 14.1.0, the following error occurs

$ gfortran -freport-bug ICE.f90
f951: internal compiler error: in gfc_find_derived_types, at fortran/symbol.cc:2458

Please submit a full bug report, with preprocessed source.
Please include the complete backtrace with any bug report.
See <https://github.com/conda-forge/ctng-compilers-feedstock/issues/new/choose> for instructions.

The source of the bug is this line, which is not valid syntax,

  re = func(1d0)%re

When the original example is compiled with ifx,

$ ifx ICE.f90
ICE.f90(4): error #6837: The leftmost part-ref in a data-ref can not be a function reference.
  re = func(1d0)%re
-------^
ICE.f90(4): error #6158: The structure-name is invalid or is missing.
  re = func(1d0)%re
-------^
compilation aborted for ICE.f90 (code 1)

The following code makes gfortran correctly identify the syntax error:

subroutine icemaker()
  implicit none
  real(kind=8) :: re
  complex(kind=8), external :: func
  re = func(1d0)%re
end subroutine icemaker
complex(kind=8) function func(x)
  real(kind=8) :: x
  func = x
end function
$ gfortran ICE.f90
ICE.f90:5:17:

    5 |   re = func(1d0)%re
      |                 1
Error: The leftmost part-ref in a data-ref cannot be a function reference at (1)

When the line

  complex(kind=8), external :: func

is removed, the internal compiler error appears again.
