[Pkg-rust-maintainers] Bug#1010083: librust-addr2line-dev: please upgrade to newer release

[Peter Michael Green]

Unfortunately it seems addr2line, gimli, object and some other packages 
are fairly closely tied together. I don't think updating them 
individually is feasible and updating the whole lot including object 
would break dwarf2sources.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=998306

Now maybe the time has come that dwarf2sources should be broken, the 
maintainer has had nearly 6 months warning to fix their package but i'm 
a little reluctant to break a package that is in Debian now for the sake 
of a package that may be in Debian at some time in the future.

With the version of addr2line currently in Debian you need to enable the 
"std" feature, it won't build with no features at all enabled. You can 
instead enable the alloc feature but that only works if the compiler is 
running in nightly mode.
