It’s indeed where the bug lies. Changing that file involves a full
rebuild (because every package build process uses it), but that’s OK:
you can test the ‘wrap-program’ procedure independently (at the REPL,
for example), and then we can push this change to ‘core-updates’.
We need to check whether ‘core-updates’ still accepts full-rebuild
changes at this stage, though.
Thanks,
Ludo’.
