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, Saul
