Breakpoints in constructor/destructor

[MONWHEA JENG <mjeng at siue dot edu>]

Hi,

	I just downloaded gdb onto cygwin. I found it pretty
wonderful, but there's one thing I'm completely baffled by. I
can't seem to set breakpoints in constructors or destructors
in my C++ programs. I wrote a simple program that does nothing but
create and destroy a simple object. When I step through it, I can see
my cout statements in the constructors and destructors being called.
But if I set breakpoints at these lines, the gdb doesn't stop there.
The program is reproduced below, but it's pretty simple---there's
not much to see. I read the gdb manual, but saw no mention of 
any special issues related to constructors and destructors. And
I see that there was a thread earlier this year on "breakpoints
in constructors," but unfortunately, I found it incomprehensible.

	Any help would be appreciated. Or, any suggestion on how
I could have figured this out on my own, from the gdb manual
or other source.
