--- Comment #1 from Sam James <sjames at gcc dot gnu.org> ---
We diagnose this from GCC 12 onwards.
$ gcc-15 -Og -g -Wall -Wextra -c test.cpp
test.cpp: In constructor ‘B::B(int)’:
test.cpp:5:11: warning: member ‘B::b’ is used uninitialized [-Wuninitialized]
5 | a(b), b(100)
| ^
test.cpp: In constructor ‘B::B(int)’:
test.cpp:5:9: warning: ‘*this.B::b’ is used uninitialized [-Wuninitialized]
5 | a(b), b(100)
| ^~~~
The output got better in 13+.
