Can confirm, it still happens with GCC/libstdc++ 13.0. However, in my case,
it's in static initializer.

We still don't have a complete description of the problem though.

If this only happens when the shared library is loaded from a closed source
application, you really need to talk to Oracle.

My best guess for what's happening in the original report is that the shared
library is being loaded into a running process which uses an older version of
libstdc++, and so the locale facets needed by the shared library were never
created at startup. When std::regex tried to use those facets, it fails to find
it.
But without a way to reproduce the problem, this will never get resolved.

I reproduced it with the game engine loading game mod, on Ubuntu Linux system.
Both the engine and the mod are open source, but I'm trying to craft a smaller
example.

Is the engine a C++ application, or C, or something else?
