[otp] io:fwrite/2 does not appear?

[krestenkrab]

It seems that even though we succeed loading and compiling io, the function fwrite/2 is not there anyway? This is strange. The module compiles and loads with no complaints; perhaps a race condition?

Duh! this is because of the dummy io module. If we remove this, then the problem goes away.

[eriksoe]

Indeed... Close this?

[krestenkrab]

Yep. closed.
