$ g++-16 l.cxx -O2 -c -Wall -Wextra -std=c++14
In member function ‘void i< <template-parameter-1-1> >::m(k*) [with ab = s]’,
inlined from ‘i< <template-parameter-1-1> >::i(i< <template-parameter-1-1>
>&) [with ab = s]’ at l.cxx:22:24,
inlined from ‘am I::u()’ at l.cxx:49:12:
l.cxx:26:3: warning: ‘a.i<s>::l’ is used uninitialized [-Wuninitialized]
26 | if (p) {
| ^~
l.cxx: In member function ‘am I::u()’:
l.cxx:49:8: note: ‘a.i<s>::l’ was declared here
49 | i<s> a = a;
| ^
is what I get on all branches now.
