Hi, On bare-metal targets (aarch64 and arm + newlib), I've noticed that the two new tests fail: PASS: experimental/algorithm/shuffle.cc (test for excess errors) spawn /aci-gcc-fsf/builds/gcc-fsf-gccsrc/obj-arm-none-eabi/gcc3/utils/bin/qemu-wrapper.sh ./shuffle.exe terminate called after throwing an instance of 'std::runtime_error' what(): random_device::random_device(const std::string&) *** EXIT code 4242 FAIL: experimental/algorithm/shuffle.cc execution test PASS: experimental/algorithm/sample-2.cc (test for excess errors) spawn /aci-gcc-fsf/builds/gcc-fsf-gccsrc/obj-arm-none-eabi/gcc3/utils/bin/qemu-wrapper.sh ./sample-2.exe terminate called after throwing an instance of 'std::runtime_error' what(): random_device::random_device(const std::string&) *** EXIT code 4242 FAIL: experimental/algorithm/sample-2.cc execution test Does this ring a bell? Thanks, Christophe
