Noam, can you please check whether building the emacs-25 branch with
HYBRID_MALLOC defined fix the problem in this bug report?  If it does,
then I think we need to arrange for HYBRID_MALLOC to be defined on ELF
based systems where DOUG_LEA_MALLOC is not defined.  I think d6585a910
on master shows the change in configure.ac which did that.  Bug#22086
holds the relevant discussions.
