Re: Warning about uninitialized members in initializer list

[Peter Doerfler <doerfler@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi Mike.

Try
g++ -Wall -Wextra testtest.cpp
testtest.cpp:9: warning: unused parameter '_i'
testtest.cpp:9: warning: unused parameter '_i'

With line 9 the constructor of B.
Both gcc3.4.4 and gcc4.0.1.

However, I thought there would be a warning with
g++ -O3 -Wuninitialized -Winit-self testtest.cpp

Can anybody explain?

Thanks
-- Peter
