Well, the "configure" code itself is okay, it's more a question of testing all the different configurations. What is really difficult, pretty much impossible, is writing code correctly without ever testing it. Plus, I think most people working on Emacs were not even aware of the ralloc configuration, so they couldn't know about the possibility of bugs from it. > Again, thank you for your e-mails. > > Emacs has been maintained in good condition by people like you. > > So thank you very much! Testing and reporting bugs is also important to maintaining Emacs, so thanks to you as well! I should mention also that this stuff is solved in Emacs 26 (not yet released), so that the standard allocater will be used once more and there won't be a need for ralloc. https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22086
