[big-r81]

We could shrink the couchjs_(mainjs|coffee).exe even more, if we remove the '-g' compiler option ...

[big-r81]

If -g helps shrink it further we can go for it. It would have to be worth it though, as -g could help if we get crash dump and there are some symbols in there.

Yeah you’re completely right. Might be easier to read these crash dumps instead of memory addresses 😜.
