[Bug]: clang crashes on aarch64 architecture under x86_64 host when using qemu-static #28
Description
Problem description
clang crashes/hangs on aarch64 architecture under x86_64 host. It seems to be an upstream issue of qemu-aarch64-static. But actually there is no such issue under other aarch64 rootfs (test with clang under alpine and ubuntu).
What steps will reproduce the bug?
pkg install clang
echo -e "#include <iostream>\nint main() { std::cout << std::endl; }" > main.cpp
clang++ main.cpp -v # hangs
clang++ -std=c++11 main.cpp -v # crashes
