Is there a way to verify if there are wrongly initialized TLS
variables in some application or I can only detect such cases when the
application fails?
Can the linker or runtime linker warn about these cases? Or because we
haven't compiled with -fpic or -ftls-model=global-dynamic, then the
runtime linker doesn't know there are TLS variables in our binary?

Thanks,
