--- Comment #3 from Antony Lewis <antony at cosmologist dot info> --- Although my reduced test in the other id case is one problem, it appears that is not the only memory leak. Someone tested else on various gcc versions and still found: version memory leak 7.3.0 no 8.2.0 no 7.5.0 yes 8.4.0 yes 9.2.0 yes 9.3.0 yes So it certainly looks like a regression.
