--- Comment #7 from Sergei Trofimovich <slyfox at inbox dot ru> ---
I had a look at it in https://bugs.gentoo.org/663690#c19

TL;DR: Gentoo has two libbfd-2.30.0.so libraries with incompatible ABIs:
    /usr/lib/binutils/i686-pc-linux-gnu/2.30/libbfd-2.30.0.so
and
    /usr/lib/libbfd-2.30.0.so
One of them is built --enable-64-bit-bfd, then other is not. Unfortunately the
have the same SONAME and the error is subtle.

Normally it's not al issue as 'ld' uses private library at
    /usr/lib/binutils/i686-pc-linux-gnu/2.30/libbfd-2.30.0.so

Unfortunately cargo(rust?) uses LD_LIBRARY_PATH=/usr/lib environment when calls
gcc/ld and tricks ld into loading wrong (ABI-incompatible) library.
