>Description:
I have problem setting breakpoints at code compiled by gcc3, but gcc-2.96 works.

Problem is, that kdevelop3, which I am using, sets breakpoint by my opinion as 'file.cpp:line' (but I am not sure) and it doesn't work. Next problem is, that I can't set breakpoint to some line in constructor and it may be distress.

With code compiled with gcc-2.96 it works fine.

How to solve this problem?
>How-To-Repeat:
cat file.cpp

#include <iostream>
using namespace std;

class C {
        public:
        C();
        ~C();
};

C::C() {    /*line 10*/
        cout << "constructor\n";    /*line 11*/
}

C::~ C() {
        cout << "destructor\n";
}

int main() {				/*line 18*/
        C c;
        return 0;
}


//compile
gcc-3.4.0 -O0 -g3 -lstdc++ file.cpp

//run gdb
gdb a.out

//set breakpoint to line 10 in file.cpp
(gdb) break file.cpp:10
Breakpoint 1 at 0x8048e90: file file.cpp, line 10.

//start
(gdb) run
Starting program: /home/msk/tmp/gdb/a.out

// DOESN'T STOP !!
constructor
destructor

Program exited normally.
quit


//but this works fine:

//run again
gdb a.out

//set breakpoint to constructor by name, NOT line number
(gdb) break C::C()
Breakpoint 1 at 0x8048eb4: file file.cpp, line 10.

//start
(gdb) run
Starting program: /home/msk/tmp/gdb/a.out

//stops OK
Breakpoint 1, C (this=0xbffff5d0) at file.cpp:11
11              cout << "constructor\n";
