The user mentioned that when running their Go test on QEMU-ARM, it sometimes hangs. They provided details about their environment: Ubuntu 16.04.5 x86_64, QEMU-ARM version 4.2.0, and Go 1.14.1 compiled for Linux/ARM. + +The test code is a simple loop that prints "Hello world" 1000 times. They ran this command 500 times in the QEMU environment, and it hung around 200-300 times. They also attached a strace log but didn't include it here. + +So, what's happening? The test runs fine most of the time but occasionally hangs. That suggests there might be some non-deterministic issue, perhaps related to timing or resource usage. Since it's in QEMU, maybe something with how system calls are handled in the emulator could be causing the problem. + +Looking at the possible categories: instruction, syscall, runtime. + +- Instruction issues would mean that a specific CPU instruction is causing problems. But since this is happening across multiple runs and not on every execution, it might not be an instruction-level bug. +- Syscall errors could happen if QEMU isn't handling certain system calls correctly, leading to hangs. Go's runtime uses syscalls for things like I/O operations, which the test does a lot of with fmt.Printf. +- Runtime issues are more general and could involve memory management or other higher-level problems in QEMU. + +Considering that the hang is related to running a Go program, which is compiled to ARM instructions but executed within an emulator on x86_64, it's possible that there's a problem in how QEMU handles certain syscalls made by the Go runtime. For example, if the emulator isn't correctly implementing a system call that Go relies on, especially under load or repeated calls, it might lead to hangs. + +Alternatively, maybe the issue is with how QEMU schedules or handles multiple processes/threads, but since this test doesn't involve concurrency beyond the loop, that's less likely. + +So, I think the most probable category here would be 'runtime' because it's a more general issue within the emulator that might not be tied to a single instruction or syscall but rather how QEMU manages execution over time. +</think> + +runtime \ No newline at end of file |
