Comment:

 Found the reason: a global env variable GHCRTS with the value -M1000M
 This would be considered as an unsafe RTS setting and therefore the
 behaviour I am seeing is the expected:

Comment:

 We won't be applying this patch.  GHC 7.2 will not generate the warning.
 In the meantime you have to disable the warning for Alex-generated code.
 Unfortunately it's not possible to make Alex do this itself, because it
 can't tell whether GHC supports the correct option (and conditional
 compilation for OPTIONS_GHC pragmas is also a recently-added feature).

 If you look through the history of the Alex repository
 ([http://darcs.haskell.org/alex]) you'll see us go back and forth on this
 issue over the last few releases.

Comment:

 Knowing whether a particular list value is infinite requires solving the
 halting problem, which is undecidable -- sorry.

Re: #180: GHCi tries to print infinite list (like [1..])

I think we are stuck with the current behaviour (which I find entirely natural). If we can anticipate infinite lists then can we not solve HP?

I believe many LISP REPLs allow the user to configure limits on
printing of lists, especially to avoid printing circular lists.

Just having a (user controllable) limit in GHCi on the number of items
of a list that is printed might be enough.

Perl is another example of filling a tiny, short-term need, and then
being a real problem in the longer term.

 Can you attach the relevant log lines from /var/log/install.log? That
 would help me get a handle on what is going wrong on your system.
