s390x binaries segfault Hello World appears to segfault with qemu s390x, on a Debian 10.0.0 Buster amd64 host. $ cat hello.cpp #include using std::cout; int main() { cout << "Hello World!\n"; return 0; } $ s390x-linux-gnu-g++ -o hello hello.cpp $ qemu-s390x-static hello Segmentation fault Does "make check-tcg" work in this case? It works for me here. Which QEMU version are you using here? Can you reproduce this issue with the latest upstream QEMU ? ... otherwise, please report this issue to the Debian bug tracker instead.
