Specific examples where musl-libc can be problematic?

[samlevin]

I've been using alpine-node for a bit and find it useful (and minimal). Great base image. In the readme, you mention:

As Alpine Linux uses musl, you may run into some issues with environments expecting glibc-like behavior – especially if you try to use binaries compiled with glibc. You should recompile these binaries to use musl (compiling on Alpine is probably the easiest way to do this).

Are there any notable/common problem areas surrounding this? So far I've read that one such example is OracleJDK 8. Are there any other common libraries (for node use-cases) that require glibc? If so, can they be fully worked-around by compiling them against musl-libc? Are there any observed instances where this caveat cannot be worked around?

It mostly affects things where there are prebuilt binaries that don't distinguish between glibc and musl – like for example https://www.npmjs.com/package/phantomjs-prebuilt

Whereas in an ideal world, companies/ppl would provide binaries prebuilt for both systems, eg: https://zeit.co/download#command-line (now-linux and now-alpine)

Thanks for the info @mhart!
