--- Comment #8 from John David Anglin <danglin at gcc dot gnu.org> ---
The issue with https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=0ee3266b3dec4d
is that it causes emacs to reallocate malloc'd data that's not 16-byte
aligned. This doesn't happen when MALLOC_ABI_ALIGNMENT is 128 bits. There
might be a bug in mremap causing the memory exhaustion.

MALLOC_ABI_ALIGNMENT should be set to 64 when we actually need 16-byte
alignment for the pthread lock. Since we no longer need 16-byte alignment
of the pthread lock structure other than for ABI compatibility, commit
https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=0ee3266b3dec4d should by
reverted.

Here are reverts:

Should be fixed.
