Bug ID: 93671
Summary: gfortran 8-10 ICE on intrinsic assignment to
allocatable derived-type component of coarray
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: damian at sourceryinstitute dot org
Target Milestone: ---
The code below generates an internal compiler error (ICE) in gfortran 8.3.0,
9.2.0, and in 10.0.0 dated 20200111.
A more complete demonstration the data structures of interest is shown in the
code example at http://bit.ly/37aHXxG, which works with the Intel Fortran
compiler version 18. I"m not clear on whether the code is standard-conforming,
but the code compiles and executes without error with the Intel compiler
version 18 as does the longer, more complex version at the aforementioned URL
executes without error.
$ cat gfortran-8-10-ice.f90
type flux_planes
integer, allocatable :: normals
end type
type package
type(flux_planes) surface_fluxes(1)
end type
type(package) mail[*], halo_data
halo_data%surface_fluxes(1)%normals = 1
mail = halo_data
end
$ gfortran -fcoarray=single gfortran-8-10-ice.f90
gfortran-8-10-ice.f90:12:0:
12 | mail = halo_data
|
internal compiler error: Segmentation fault: 11
libbacktrace could not find executable to open
