I build gdb 14.1 release on aarch64-linux, and used the x86_64 a.out from the
attachment to reproduce the problem.

> $ g++ -std=c++20 -Wall -g -O3 read.cpp

Reproduced from source on x86_64-linux.

Also managed to reproduce at O2 by adding two O3 settings (as found in
gcc/opts.cc):
...
$ g++-13 -std=c++20 -Wall -g -O2 --param=max-inline-insns-auto=30
--param=inline-heuristics-hint-percent=600 read.cpp
