Here is a dead simple reduced version:
```
% cat pr111522.cc
#include
#include
#pragma GCC push_options
#pragma GCC target "cpu=power10"
float BitCast(int in) {
float out;
memcpy(&out, &in, sizeo

--- Comment #10 from Mathieu Malaterre ---
for reference:
% c++ --verbose -O2 -flto base2.cc && ./a.out
Using built-in specs.

--- Comment #9 from Mathieu Malaterre ---
If you download pr111522.cc from comment #8, you should be able to reproduce
exactly the original upstream issue.
Steps:
% c++ -O2 -flto pr111522.cc && ./a.out
vs
% c++ -O2 pr111522.cc && ./a.out

Those global vars are in different namespace, I actually fail to underwhat why
