> Also, I've never seen a failure to report whats wrong.
Yes, but I have always seen a failure to report what has failed.
But here, there is simply nothing in the log. It simply says that some
tests failed, but not WHICH test failed, not what was the expected output
and the actual output, not whether there has been a crash. Absolutely
nothing.
> Can you post the full log?
Not before Monday (bandwidth).
Anyway, the verbose output above indicates that we have numerical noise,
not related with Singular. By the way, if that's relevant: In my local
branch I have merged your gdb branch from #16978.
