--- Comment #52 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> --- (In reply to Jakub Jelinek from comment #51) > Your assumption is wrong, reductions are not handled in libgomp, but in the > code emitted by the compiler. does this imply that the combination of -fsanitize=thread and a libgomp as obtained with --disable-linux-futex is indeed a 'proper' solution for this PR, or do you think that building two libraries such as suggested in comment #42 would be best ?
