It's best to file a bug report so we can: a) discuss the validity of the testcase, and b) reference it in review of the commit & even once it is in .. but that said, I thought this looked familiar, and I found PR117695 which is marked as INVALID. > [...] FWIW, all the analysis should go in the commit message, as well as including a testcase in the commit itself. The commit message should also have a ChangeLog. See these links: * https://gcc.gnu.org/contribute.html * https://gcc.gnu.org/codingconventions.html But these are general remarks. I can't approve the patch (that is for others) but I'm not sure if the testcase is valid anyway. > [...] thanks, sam
