--- Comment #12 from Liviu Ionescu <ilg at livius dot net> --- However Debian 12 is not that old, what might be wrong with it? The initial report is based on a Debian 12 run. I did another run on a physical Debian 12 and the issue is reproducible on my machine. Isn't it possible to fix libstdc++ in order to run static multi-threaded apps on older systems too?
