I asked to post the patch and discuss it before committing, as these are delicate issues where I prefer that we all are on the same page before changing this code. > WRT Lisp_Object allocas, please tell if I should do that. Let's discuss this on a case by case basis. Not all uses of alloca are the same or have the same requirements and restrictions. > (I think this all could also be done on master, but since this is there > forever, I don't think it's absolutely necessary. Agree?) Exactly my point, which is why I think we should discuss these changes before installing them on the branch, let alone on master.
