* [Bug c++/40173] New: Calling a constructor from another constructor of the same class

Command line: g++ -pedantic -Wall -o test test.cpp
Compiler output: none
Basically, I created a class with two constructors. One of those is
trying to call the other one. The call doesn't seem to have any effect
at all.
The problem is: g++ allows such a thing with no warnings at all.
Apart from that, I believe such functionality might be useful. For
example, if we've got a constructor with one parameter and quite a
heavy block of code, along with another constructor that takes no
arguments - which we'd like to be a wrapper for the first one, passing
some kind of default value to it.
Thanks for your time ;)

Yes it does, it creates another object and calls that constructor.

Note, in the next C++ Standard, what the user wants will be possible, see,
