Bug ID: 93458
Summary: ICE using coroutines
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tromey at gcc dot gnu.org
Target Milestone: ---
I'm using git master gcc from today.
I tried a simple coroutine program:
int func(int *x) {
for (int i = 0; i < 23; ++i)
co_yield x[i];
}
Compiling causes gcc to ICE:
murgatroyd. ./install/bin/g++ -fcoroutines -g -c -o /tmp/qq.o /tmp/qq.cc
/tmp/qq.cc: In function ‘int func(int*)’:
/tmp/qq.cc:3:5: error: cannot find ‘coroutine traits’ template
3 | co_yield x[i];
| ^~~~~~~~
/tmp/qq.cc:3:17: internal compiler error: in coro_promise_type_found_p, at
cp/coroutines.cc:390
3 | co_yield x[i];
| ^
