Dear Paul,
Indeed I confirm that "happy" provided by Debian buster/sid does not work
on my hardware (armv5tel Kirkwood Feroceon). Just tested now after removing
Ilias' deb package and reinstalling the previous one:
drakestail:/opt/bug_ghc_armel# apt remove happy
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
happy
0 upgraded, 0 newly installed, 1 to remove and 1 not upgraded.
After this operation, 2,598 kB disk space will be freed.
Do you want to continue? [Y/n]
