--- Comment #2 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to Iain Sandoe from comment #1) > note that a default size of 8Mb is not enough for either Linux or Arm64 > Darwin (both have PTHREAD_STACK_MIN of 16384). this is, of course, rubbish .. the default is 8Mb not 8k (which is fine for both 4096 and 16384 page sizes).
