[Pkg-rust-maintainers] Bug#1040477: librust-syn-1-dev fails to coinstall

[Johannes Schauer Marin Rodrigues]

Hi,

Quoting Helmut Grohne (2023-07-06 13:27:19)

this looks very bad.

I'd be very interested in knowing what this self-conflict is supposed to
achieve. Depending on the answer it might be worth adding a Lintian check so
that this doesn't happen again in the future.

Thanks!

cheers, josch
