I'm trying to compile a program that is using a MALLOC_OPTIONS of "A" which doesn't exist. Reading the manual all of the options look good to me so what would be the best? I'm going to go with "S" unless otherwise instructed. Thanks, Edgar

Cost of malloc options

A couple of weeks ago, I ran a bunch of make builds (ncpu=4 amd64) with different malloc() options enabled. I don't want to spawn a discussion, but for anybody who's curious, and for the archives, here are the results: 36m17.68s real47m33.50s user26m49.97

Note that you can also set the malloc options from within a program you are developing. I've found this to be quite useful for adding a "belt and suspenders" mode during developement (the use after free checks in particular). - todd
