Then, gcc still "compiles" them, but all the declarations are missing. And I would expect gcc to complain if zero blocks returned, and truncated files are very likely to abort compilation. Can the command be strace'd immediately after the failure? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
