Bug ID: 90499
Summary: ICE during polymorphic assignment
Product: gcc
Version: 8.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: townsend at astro dot wisc.edu
Target Milestone: ---
The test program below causes an internal compiler error, that appears to be
linked to the polymorphic assignment:
--
program test
implicit none
type f_t
end type f_t
type, extends (f_t) :: g_t
end type g_t
contains
function func () result (f)
class(f_t), allocatable :: f
f = g_t()
end function func
end program test
--
When compiling with gfortran -c test.f90, I get:
test.f90:17:0:
f = g_t()
internal compiler error: in build_function_decl, at fortran/trans-decl.c:2242
libbacktrace could not find executable to open
Please submit a full bug report,
