It's not a solution, it was a work-around. FWIW, I have tried to build the package with the gcc-10 package from Debian (which is a recent snapshot) and -mlra, but so far cmake doesn't want to accept gcc-10 as the build compiler when set with export CC/CXX, so I have to poke around what the problem is. I will report back once I have a result.
