大家,在gdb中使用“next”指令时,我发现每行源代码显示两次-----我很确定,这些代码没有在任何循环中。这是现象:
(gdb) frame
#0 ap_get_client_block (r=0x8560d48,
buffer=0xb68501b7 "<?xml version=\"1.0\" encoding=\"utf-8\"?><Root><OperCode>SMS101</OperCode><AppId>SMSMsgFilterReq</AppId><Req><UserMobile>13925237429</UserMobile><SendMsg>abc圲34¨圲23a露07\214圲21¢<237朲11?东215圲10°<214朲27¥応227露07\214正常,hao"..., bufsiz=81920) at http_filters.c:1540

(gdb) n
1544 bb = apr_brigade_create(r->pool, r->connection->bucket_alloc);
(gdb)
1545 if (bb == NULL) {
(gdb)
1544 bb = apr_brigade_create(r->pool, r->connection->bucket_alloc);
(gdb)
1545 if (bb == NULL) {
-----第 1544,1545 行没有在任何循环中,但它们被重复了。有人可以启发我吗?
