--- Comment #12 from ofv at wanadoo dot es --- I don't see other failure messages on the previous dozens of lines but, if they exist, they are not deemed serious enough to stop the build by the build system. BTW, we successfully built gcc-11-dwarf with gcc-10-sjlj. Now we will see if the resulting binaries work for bootstrapping gcc-11. That would suggest that there is a problem with 10 and it is fixed/masked/whatever on 11.
