When linking rust code compiled with coverage enabled, we see `error: duplicate
symbol: __gcov_dump` and similar.
Bisection points to 8f91f38 <a href="https://reviews.llvm.org/D86142">https://reviews.llvm.org/D86142</a> which is odd
because at first glance I wouldn't think that patch should affect non-fortran.
Should those gcov symbols have been considered mergeable?
Our build setup is pretty complex and I'm still trying to understand the
failure better, but I wanted to report this as early as possible given the
12.0.0 timeline. Right now I only have the CI logs but I'll try reproducing it
locally. If there are any specific pieces of information that I should try to
extract to help people debug this, please let me know.</pre>
