Precompilation fails in Julia 1.6.7 (current LTS)

[jonas-schulze]

Adding TranscodingStreams to a fresh environment using the current Julia LTS fails. The last version that succeeded is v0.5. I noticed this behavior trying to use MAT (JuliaIO/MAT.jl#179), which got TranscodingStreams as a depency via CodecZlib.

Are you using a custom system image?

No, I used the x86 download from julialang.org .... however, with a fresh ~/.julia I can no longer reproduce either. Unless this is smth worth investigating, feel free to close the GitHub issue. With my old ~/.julia I still can reproduce the failure, even with v0.9.12 instead of v0.9.11. The oldest Julia that has ever lived on my computer is 1.6.7, but the ~/.julia is shared between 1.6.7, 1.7.3 (barely used), and 1.8.5.
