Antoine Pitrou <pitrou at free dot fr> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pitrou at free dot fr --- Comment #7 from Antoine Pitrou <pitrou at free dot fr> --- I wanted to chime in to say that we've encountered this on the Apache Arrow CI: https://github.com/apache/arrow/issues/47015#issuecomment-3045686189 It seems this comment is mistaken as GCC 13.3, at least, still uses pthread_once for std::call_once: > This should be fixed in GCC 11 which no longer uses pthread_once for > std::call_once.
