I simulated building current Emacs on future glibc by running './configure emacs_cv_var_doug_lea_malloc=no', which tells 'configure' to assume that the C library does not have the GNU malloc extensions. Although the code still seemed to work, there were some compile-time errors that suggested trouble; for example, glibc's API for the malloc hooks disagree with Emacs's replacement. To fix this I would like to install the set of patches discussed for Bug#22086, here:
