Yes I am sure.
See g++ vs clang++
g++-14 -O0 -std=c++17 -Wall -Wextra -Wpedantic -Wuninitialized
-fno-strict-aliasing -fwrapv -g3 test.cpp && ./a.out
test.cpp: In function ‘int main()’:
test.cpp:55:10: warning: variable ‘reader’ set but not used
[-Wunused-but-set-variable]
55 | auto reader = Reader("file", 1);
| ^~~~~~
[1] 505165 segmentation fault (core dumped) ./a.out
clang++ -O0 -std=c++17 -Wall -Wextra -Wpedantic -Wuninitialized
-fno-strict-aliasing -fwrapv -g3 test.cpp && ./a.out
test.cpp:51:9: warning: private field 'l_' is not used [-Wunused-private-field]

terminate called after throwing an instance of 'int'
[1] 505364 abort (core dumped) ./a.out
I also have confirmation that this happens for someone else too with my
reproduction attachment on another pi5, see
