Sorry, I've lost context. What's "this"? Doesn't draft Emacs 25.2 work=20 adequately on bleeding-edge glibc without our doing anything special? If = not,=20 what are the problems and how can we reproduce them? I attempted to reproduce the problems, whatever they are, by building dra= ft=20 Emacs 25.2 with './configure emacs_cv_var_doug_lea_malloc=3Dno' on x86-64= Ubuntu=20 16.04.1 (I don't have easy access to 16.10 yet, but this does build and l= ink=20 gmalloc.o and ralloc.o). --enable-gcc-warnings did generate some warnings= , which=20 I just now fixed, but I didn't observe any runtime misbehaviors.
