[Pkg-haskell-maintainers] Bug#650808: frown: OOM on compiling any remotely valid grammer

[Helmut Grohne]

Package: frown
Version: 0.6.1-11
Severity: grave
Justification: renders package unusable

I noticed that frown would no longer translate my projects, because it
would eat too much memory. So I tried to come up with smaller grammers.
I arrived at

$ cat test.lg
> %{
> }&
$

Now this didn't eat any less memory, but maybe 1G is too little.
Thankfully Tolimar volunteered to test this with 8G and suprisingly it
ate those 8G as well. I can only conclude that frown is no longer able
to compile any grammer in any reasonable amount of memory. This renders
the package unusable for any normal user.
