They're experiencing issues when building Go applications that involve multiple threads—specifically, segmentation faults and hangs. When they limit Go to use only one thread (GOMAXPROCS=1), the problem doesn't occur. + +The steps to reproduce show that the Dockerfile sets up a PPC64LE environment using QEMU as an emulator. The problem arises when multi-threaded commands like `go build` are run inside this container. + +I remember that user-mode emulation by QEMU is responsible for running applications compiled for different architectures. It handles system calls and thread management in user space. Multi-threading issues often point to problems with how threads are scheduled or resources are managed within the emulator's context. + +Since the problem occurs when multiple threads are used, it suggests an issue with how QEMU manages these threads in user-mode. The fact that single-threaded operations work but multi-threaded ones fail points towards a concurrency bug within the user-mode layer of QEMU. It might be struggling to handle multiple goroutines correctly under emulation. + +Additionally, the error messages mention unexpected signals during runtime execution and a stopm holding locks, which are related to Go's runtime handling of threads. These issues likely stem from how QEMU is emulating the thread operations in this environment. + +Given that system-mode would involve more底层硬件模拟，比如设备驱动和操作系统层面的问题，而这里的问题更偏向于应用程序在用户空间的执行问题，尤其是多线程处理。因此，这个bug更可能属于user-mode相关。 +</think> + +user \ No newline at end of file |
