Describe the Bug

希望hook Android libbase.so android::base::LogMessage::LogMessage构造函数，hook代码如下： `namespace android { namespace base {

    enum LogSeverity {
        VERBOSE,
        DEBUG,
        INFO,
        WARNING,
        ERROR,
        FATAL_WITHOUT_ABORT,
        FATAL,
    };

    enum LogId {
        DEFAULT,
        MAIN,
        SYSTEM,
    };

    void LogMessage(const char *file, unsigned int line, LogId id, LogSeverity severity,
                    const char *tag, int error) {
        BYTEHOOK_STACK_SCOPE();
        ALOGD("LogMessage %s",file);
        BYTEHOOK_CALL_PREV(LogMessage, file, line, id, severity, tag, error);
    }

    void HookCallback(bytehook_stub_t task_stub, int status,
                      const char *caller_path_name, const char *sym_name,
                      void *new_func, void *prev_func, void *hooked_arg) {
        ALOGE("hook: %s-%s-%d", caller_path_name, sym_name, status);
    }

    void hook(){
        bytehook_hook_single("libart.so", "libbase.so",
                "_ZN7android4base10LogMessageC2EPKcjNS0_5LogIdENS0_11LogSeverityES3_i",
                             reinterpret_cast<void *>(LogMessage), HookCallback, NULL);
   }
}

}`

然后时间运行时在BYTEHOOK_CALL_PREV调用原函数时会崩溃，崩溃栈如下：

大佬帮忙看下是怎么回事啊

改成这样试试：

void* LogMessage(void *thiz, void *const char *file, unsigned int line, int id, int severity, const char *tag, int error) {
    BYTEHOOK_STACK_SCOPE();
    ALOGD("LogMessage %s",file);
    return BYTEHOOK_CALL_PREV(LogMessage, thiz, file, line, id, severity, tag, error);
}
