调试的时候总是出现下面这种情况,代码跳来跳去, 烦死了

51          ckHeader = readChunkHeader(chunkOff, fileNum);
(gdb)
49          chunkOff = idx->offset1;
(gdb)
51          ckHeader = readChunkHeader(chunkOff, fileNum);
(gdb)
49          chunkOff = idx->offset1;
(gdb)
51          ckHeader = readChunkHeader(chunkOff, fileNum);
(gdb)
52          postNum += ckHeader.postNum;
(gdb)
51          ckHeader = readChunkHeader(chunkOff, fileNum);
(gdb)
52          postNum += ckHeader.postNum;
(gdb)
51          ckHeader = readChunkHeader(chunkOff, fileNum);
(gdb)
55              printf("chunkOff=%u, fileNum=%u n", chunkOff, fileNum);
(gdb)

疑似是代码优化问题。

调试代码记住要用-g -O0编译。
