Hi, I think what you are seeing is basically a consequence of building an older version of gollvm -- the version you are building doesn't include newer bug fixes in the gofrontend version of the go command. The fix you need is in a gofrontend commit ( c948c2d770122932a05b62f653efa2c51f72d3ae ) that dates to fall of 2020. The older version of gofrontend you are picking up doesn't include this fix.
Not sure if there is an easy workaround here-- when building older versions of the tools you have to be prepared for this sort of thing. I am sure that there are LLVM bugs fixed in version 11 that are still present in V10, for example.
