Clang 11.0.0 CUDA compiler bug: tuple conversion constructor (fixed in 11.0.1) #1615

Open havogt opened 3 years ago

havogt commented 3 years ago

The following program crashes Clang 11.0.0 (in the Cray provided version, however -fno-cray, -fno-cray-gpu doesn't fix it):

#include <gridtools/common/tuple.hpp>
__global__ void test_kernel() {
    gridtools::tuple<int, double> tpl{'a', 'b'};
}

Seems to be fixed in Clang 11.0.1 (tested on my notebook), but could also be related to the Cray wrapper or daint specific setup.

This particular test is disabled in #1613 for Clang 11.0.0.

Let's keep this issue open until daint has a newer version with a fix.
