Bug ID: 121639
Summary: [OpenMP] ICE when trying to map a member variable of
reference type
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, openmp
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
CC: tschwinge at gcc dot gnu.org
Target Milestone: ---
Reference members should automatically get mapped alongside mapping the
struct/class itself.
The ICE shows up in gcc/tree.cc:15210's
verify_type_context (loc=75530114, context=TCTX_OMP_MAP, type=0x0,
silent_p=false)
15210 gcc_assert (TYPE_P (type));
(gdb) p type
$1 = (const_tree) 0x0
----------------------------
#include <stdio.h>
int x;
struct s {
int &xr = x;
void f() {
// #pragma omp target map(xr) // -> ICE (1)
// #pragma omp target map(this->xr) // -> ICE (2)
// #pragma omp target map(this[:1]) // -> ICE (4)
#pragma omp target // -> ICE (3)
__builtin_printf("%pp\n", &xr);
}
};
int main()
{
struct s x;
x.f();
}
