Summary: ICE/segfault during parsing with modules and invalid
code in gfc_free_namespace when using the same symbol
twice
Product: gcc

Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
f951: internal compiler error: in gfc_free_namespace, at fortran/symbol.cc:4039
0x686c77 gfc_free_namespace(gfc_namespace*&)

for the invalid attached testcase. -fopenmp is in theory required.
There are two issues:
* The same symbol is used twice, once use associated and once newly defined
in an interface block.
* There is a tailing '::'
module omp_lib_target
use omp_lib
implicit none (type, external)
interface
logical function omp_target_is_present(ptr, device_num)
type(*), dimension(..) ::
end function omp_target_is_present
end interface
end module omp_lib_target
