A question in using gdb

[杨冬]

gnu，您好！

             hi~~
         I'm a c++ developer under Linux platform in china. Today I encountered 
a strange question described as belows:
         I define a function in class CRecordProcess_CDR named init() in file 
loadindex_recordprocess.cpp. When I want to break at that function using this 
command: b CRecordProcess_CDR::init, the return clue exhibits me that a 
different fuction is breaked.
         (gdb) b CRecordProcess_CDR::init()
                 Breakpoint 9 at 0x10007f30: file library/library_time.cpp, 
line 23.
         I don't know why the gdb go to this function in a different file.
         Further more, whenever I want to go into any functions in file 
loadindex_recordprocess.cpp with gdb, I received such return information:
         Breakpoint 9, 0x0000000010007f30 in ._ZN18CRecordProcess_CDR4initEv () 
at /usr/include/c++/3.2.3/new:88
         88      // Default placement versions of operator new.
         (gdb) n
         0x0000000010007f20      88      // Default placement versions of 
operator new.
         (gdb) n
         0x0000000010007f24      88      // Default placement versions of 
operator new.
         (gdb) 
         0x0000000010007f28      88      // Default placement versions of 
operator new.
         (gdb) 
         0x0000000010007f2c      88      // Default placement versions of 
operator new.
         (gdb) 
         0x0000000010007f30      88      // Default placement versions of 
operator new.

         After a long time of such information when the program jumped out of 
the function in file loadindex_recordprocess.cpp and entered into other 
fuctions in other files, everything goes well.I don't know what had happened 
and how to slove it. Can you give me some clues?
         Any help are appreciated. Thanks a lot!!!

                                                                                
                                                                                
                                                yours 
                                                                                
                        dong yang
