Hi,

After perusing the texmfcnf.lua file, I created a file with the same name
in my texmf-local folder, changing the settings for the node memory and
step size, but it did not affect the compilation of the original MWE
(without the enableexperiments switches), which still fails.  What am I
missing?

Below the contents of the file:

return {
   content = {
directives = {
       ["luametatex.nodesize"] = { size = 60000000, step =  600000 },
}
  }
}

Todas as coisas fatigam o corpo, salvo a música, que não fatiga nem o corpo
nem seus membros, por ser descanso da alma, primavera do coração, distração
do aflito, entretenimento do solitário, e viático do viajante.
