This version of nheko was just rebuilt 18 days ago as a binNMU.
https://buildd.debian.org/status/fetch.php?pkg=nheko&arch=amd64&ver=0.7.2-3%2Bb1&stamp=1609589163&raw=0
That build used gcc-10_10.2.1-3 instead of gcc-10_10.2.1-6.  Given that
the package was built successfully so recently, I suspect that there is
a bug elsewhere, but aside from blindly reassigning this bug to gcc-10
and crossing my fingers, I'm not sure what's the best way to proceed.
But I've Cc'ed doko, as gcc maintainer, on this email.

Coincidentally, I uploaded nheko 0.8.0 today, and it also failed in the
same spot (/usr/include/tweeny/easingresolve.h:62:27).  In fact, I
thought that this bug was about the newly-uploaded package, until I
looked more closely at it. ;)  It succeeded to build on my own machine,
which was using an older version of gcc (9.3.0, apparently).
