Bug ID: 92763
Summary: ICE in dwarf2out_abstract_function, at
dwarf2out.c:22659, or in force_type_die, at
dwarf2out.c:26224
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
g++-10.0.0-alpha20191201 snapshot (r278886), 9.2, 8.3, 7.5 all ICE when
compiling the following testcase reduced from
libgomp/testsuite/libgomp.c++/udr-21.C w/ -O1 -fopenmp
-fno-var-tracking-assignments -g:
struct A
{
typedef int T;
#pragma omp declare reduction (y : T : [&omp_out, &omp_in]() { omp_out +=
omp_in; return 0; }()) initializer (omp_priv = [omp_orig]() { return omp_orig;
}())
static void foo ();
};
void

int r = 0, s = 0;
#pragma omp parallel for reduction (y : r, s)
for (int i = 0; i < 1; i++)
