The user provided some detailed information, including the command line used, back traces from gdb, and strace logs. Let me try to unpack this step by step. + +First, the issue occurs when running QEMU in a chroot environment with specific compile options. The command given is using qemu-arm to execute edje_cc, which suggests it's compiling some EDC files for an embedded system, perhaps related to Tizen. + +The back trace shows that the process is stuck in safe_pselect6, which is part of the syscall handling in QEMU. From the gdb output, it looks like the function calls are going through safe_syscall_end and into do_select. The strace logs indicate that there's a pselect6 call with 10 file descriptors, but it seems to be hanging. + +The user mentioned that this happens occasionally—only one occurrence out of over 50 trials. That suggests it might not be straightforward to reproduce, which is challenging for debugging. They also noted that both version 2.7.0-rc4 and the stable v2.6.0 have the same problem. + +Looking at the possible categories: instruction, syscall, runtime. The issue seems to be related to how QEMU handles system calls, specifically pselect. Since pselect is a Linux syscall used for I/O multiplexing, perhaps there's an issue in how QEMU emulates or interacts with this syscall. + +The fact that it's hanging in the pselect6 call suggests a possible deadlock or incorrect handling of file descriptors within QEMU. Maybe there's an issue with how the file descriptors are managed when performing select operations, leading to the process getting stuck waiting indefinitely for I/O events that never occur. + +Considering the category options: + +- **Instruction**: This would be if there was an issue with specific CPU instructions or translation errors. But the back trace points to syscalls, not instruction-level issues. + +- **Syscall**: Since pselect is a syscall and the problem occurs during its execution within QEMU's emulation of it, this seems relevant. The bug report mentions that the hang happens in a syscall (pselect6), which fits into this category. + +- **Runtime**: This would be broader errors that happen during runtime but aren't tied to specific syscalls or instructions. However, since the issue is clearly linked to a specific syscall, it's more precise to categorize it under syscall. + +So, putting it all together, the bug report describes an error related to handling a system call (pselect6) within QEMU, leading to a hang. Therefore, the appropriate category is 'syscall'. +</think> + +The issue reported is due to a problem with handling the `pselect6` system call in QEMU, causing a hang. This falls under the syscall category. + +**Answer:** +syscall \ No newline at end of file |
