※ 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

Program received signal SIGSEGV, Segmentation fault.
0x0805505c in __static_initialization_and_destruction_0 (__initialize_p=Cannot access memory at address 0xbfe57790

(gdb) up

(gdb) where

那就麻煩老師了。

推 ric2k1:也許你在 BddMgr 的 constructor 裡 access 了不該 access
→ ric2k1:的 memory
→ waytin:我不太懂，它在BddMgr* bddMgr = new BddMgr; 這行就爆了
→ waytin:constructor只呼叫void init這應該沒問題啊
推 ric2k1:把這行 comment 掉, 換到其他global 的地方執行看看...
→ waytin:老師 comment掉就不會過了＝ ＝
