Hello, Let me ask one question I'm struggling with. I found a problem when using xmlFree(). When xmlFree() is called, I think thead look like being hanged. So, I put two debug message as following. printf("Debug message #1 \n"); xmlFree( Buffer ); printf("Debug message #2 \n"); Then I can see only the first debug message. So I tried to track this more with GDB. And the result is as following. gdb) next 950 xmlFree( Buffer ); (gdb) stepi 0x0809b11a 950 xmlFree( Buffer ); (gdb) stepi 0x0809b11d 950 xmlFree( Buffer ); (gdb) stepi 0xb7b0d5a0 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5a1 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5a3 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5a6 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5a9 in free () from /lib/libc.so.6 (gdb) si 0xb7ab6db0 in __i686.get_pc_thunk.bx () from /lib/libc.so.6 (gdb) si 0xb7ab6db3 in __i686.get_pc_thunk.bx () from /lib/libc.so.6 (gdb) si 0xb7b0d5ae in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5b4 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5b7 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5ba in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5bd in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5c3 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5c5 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5c7 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5e2 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5e4 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5e6 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5e9 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5ec in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5ef in free () from /lib/libc.so.6< BR>(gdb) si 0xb7b0d5f1 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5f3 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5f5 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5fb in free () from /lib/libc.so.6 (gdb) si 0xb7b0d5fd in free () from /lib/libc.so.6 (gdb) si 0xb7b0d604 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d607 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d609 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d60b in free () from /lib/libc.so.6 (gdb) si 0xb7b0d610 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d618 in free () from /lib/libc.so.6 (gdb) si 0xb7b0d61a in free () from /lib/libc.so.6 (gdb) si 0xb7b0d61e in free () from /lib/libc.so.6 (gdb) si 0xb7b0e377 in _L_lock_14919 () from /lib/libc.so.6 (gdb) si 0xb7b0e379 in _L_lock_14919 () from /lib/libc.so.6 (gdb) si 0xb7b809e0 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809e1 in __lll_mutex_l ock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809e2 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809e3 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809e8 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809ea in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809ec in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809ee in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f0 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f9 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809fb in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809fd in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809ff in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f2 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f7 in __lll_mutex_lock_wait () from /lib/libc. so.6 (gdb) si 0xb7b809f9 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809fb in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809fd in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809ff in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f2 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f7 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f9 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809fb in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809fd in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809ff in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f2 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f7 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809f9 in __lll_mutex_lock_wait () from /lib/libc.so.6 (gdb) si 0xb7b809fb in __lll_mutex_lo ck_wait () from /lib/libc.so.6 (gdb) Now I'm using libxml2-2.6.31-1 and libxml2-python-2.6.31-1. And one more thing is this program is working well on single core platfrom and 2 x single core (with hyperthreading) platform but it is not working on 2 x quadcore platform and makes problem as above. Could you give me any suggestion to solve this? Thanks in advance. Jason, 최소한의 공간에서 최대한의 정보 제공, live.com에 검색 결과 저장 기능 등으로 무장한 Live Search! 간편하고 정확한 나만의 맞춤 검색, Live Search! |
