The user is reporting an issue with QEMU's aarch64 emulator where the MTE (Memory Tag Extension) isn't reporting a tag mismatch as expected. They ran a GCC test case using QEMU 6.0 as a simulator, and the test failed with a segmentation fault instead of the expected tag-mismatch error from HWAddressSanitizer. + +Looking at the error message, the test expects a "tag-mismatch" error, but QEMU is generating a SEGV (segmentation fault). The problem seems to be in the QEMU environment because the test is run through qemu-aarch64. The backtrace points to the QEMU code when handling the signal (like in HwasanOnSIGTRAP), which suggests that QEMU isn't properly emulating the MTE behavior that would trigger a tag mismatch error in the sanitizer. + +The categories given are instruction, syscall, or runtime. + +- Instruction would relate to incorrect execution of a specific CPU instruction. The error here might be due to QEMU not correctly handling the MTE instructions, but the report is about a tag mismatch not being detected, which is more about the runtime behavior rather than a specific instruction. + +- Syscall would involve system calls. The error here is happening within the sanitizer's runtime code, not during a system call. The backtrace shows it's in the hwasan code, which is part of the runtime instrumentation. + +- Runtime errors are other issues that occur during the execution of the program, especially those related to runtime environments or libraries. Since QEMU's role here is to simulate the hardware environment (like MTE), and the error is in how the runtime (HWASan) is handling the MTE tags during execution, this seems like a runtime issue. QEMU might not be passing the correct information when a tag mismatch occurs, leading the sanitizer to not report it properly and instead causing a SEGV. + +So the bug is in QEMU's runtime emulation of MTE, leading to incorrect error reporting. Therefore, the category is runtime. +</think> + +runtime \ No newline at end of file |
