Yes, exactly ... this commit introduced the regression.
OK, I've regressed the branches then - I'll fix that.
This should fix it. I'll finish testing and commit it.
Sebastian, your patch to define HAVE_ALIGNED_ALLOC is OK for
gcc-7-branch and gcc-8-branch, because changing newlib from using
memalign to aligned_alloc is safe.
Should I check in my patch in addition to your patch?
Yes please, on trunk and 7 and 8. It's better to use the standard
aligned_alloc if available.
