The Itanium ISA was an infamous failure, never seeing widespread usage, hence people often referring to it as “The Itanic” (i.e. the much-touted ship that immediately sunk). The fact that anyone would be using it today at all is sort of hilariously niche, and is illustrative of how wide-ranging and obscure the issues filed to the GitHub repo could be. On a similar token I recall seeing an issue (or maybe it was a PR?) to fix our build on GNU Herd.
