[BUG] breakpoints in constructor

[Thomas Richter <thor at mail dot math dot tu-berlin dot de>]

Hi folks,

gdb 6.6 (still, *sigh*) fails to set break points in constructors within
C++ objects.

Here's a source code to test this with:

/* snip */

class A {
  //
  int x;
public:
  A(int i)
  {
    x = i;
  }
  ~A(void)
  {
  }
  //
  int getA(void) const
  {
    return x;
  }
};

int main(int argc,char **argv)
{
  A a(5);

  return a.getA();
}

/* snip */

Compile this with:

thor@mersenne:~/src> g++-4.1 -O0 -fno-inline -ggdb3 gdbtest.cpp -o gdbtest

just to be on the safe side that we get all the debugging needed and no
optimization that could confuse the debugger.

Then, launch gdb and set a breakpoint:

thor@mersenne:~/src> gdb gdbtest

(gdb) break A::A
(gdb) run
Starting program: /homes/mathphys/thor/src/gdbtest 

Program exited with code 05.
(gdb) quit

No breakpoint hit, the code just continues to run. This makes it pretty
hard to debug C++ code, especially with RAII classes where all the interesting
stuff happens in the constructor.

Any thoughts?
