FYI, I'm seeing zero effect when playing around with these things in my code base (with or without NDBUG, and the various assert macro implementations.
I'm surprised though that the small asm.js is just 57 KByte uncompressed despite using iostreams, when I tested iostream stuff in my code it was always around 400 KByte like the big test case, and this was caused by all the iostream static initializers that were pulled in. Maybe something causes the iostream init code to be stripped away? Cheers, -Floh. Am Dienstag, 18. Juli 2017 14:22:50 UTC+2 schrieb jj: > > Interesting test case.
