Infinite loop in readbytes!(s, UInt8[], 1)

[nhz2]

Here is an example that goes into an infinite loop:

julia> using TranscodingStreams

julia> s = NoopStream(IOBuffer("abc"));

julia> readbytes!(s, UInt8[], 1)

The issue is

TranscodingStreams.jl/src/stream.jl

Line 415 in fc11ad7

resize!(b, min(length(b) * 2, nb))

if length(b) is 0 then the b stays the same size.
