Hi, Mike!

I'm looking at this and previous bug (https://bugs.x2go.org/777) and can't stop wondering whether applications should really contain workarounds for bugs in system libraries. Isn't it better to just depend on newer version of library (that has fixes for currently known bugs)?

There are a lot of older bugs in glibc (that are fixed in current version), does it mean that applications should be bloated with workarounds for such bugs just in order to work more safely on machines where users don't pay enough attention to updates?

That is a true way of reasoning...

However, gethostbyname is deprecated in glibc and not really IPv4/IPv6
compliant [1].
