※ 引述《waytin (waytin)》之銘言：
: 用gdb找到以下這個
: Program received signal SIGSEGV, Segmentation fault.
: 0x08055054 in __static_initialization_and_destruction_0 (__initialize_p=Cannot access memory at address 0xbfa29360
: ) at bddMgr.cpp:19
: 19 BddMgr* bddMgr = new BddMgr;
: 打up他說不能access...
: 請問這是什麼問題啊？
(gdb) run
Starting program: /export/home/B94/b94901076/programming/project/bdd/bdd

(gdb) up

(gdb) where

那就麻煩老師了。

1F：推 ric2k1:也許你在 BddMgr 的 constructor 裡 access 了不該 access 06/24 21:20
2F：→ ric2k1:的 memory 06/24 21:20
3F：→ waytin:我不太懂，它在BddMgr* bddMgr = new BddMgr; 這行就爆了 06/24 21:23
4F：→ waytin:constructor只呼叫void init這應該沒問題啊 06/24 21:23
5F：推 ric2k1:把這行 comment 掉, 換到其他global 的地方執行看看... 06/24 21:50
6F：→ waytin:老師 comment掉就不會過了＝ ＝ 06/24 22:04
