Comment:

 I couldn't reproduce the problem with 6.8.2, but I have now added the
 program as test `simplrun010` nevertheless.

 Merged. Still need to make the test.

 Ian: please merge.  And could you make this program into a test?  (Compile
 with -O2 and run as above.)  Thanks

 Simon

Comment:

 Thanks Neil, I think we have enough to go on.  (hint: the binding `f34` is
 an infinite loop, avoiding that somehow will probably work around the
 problem).

 Simon: let's discuss this one next week, I have some suspicious-looking
 entrails but I'm not entirely sure where to place the blame.

Comment (by NeilMitchell):

 I should point out that I'm fairly certain that this code doesn't do what
 it was intended to (the tak benchmark), but it still shouldn't segfault.

 Windows XP. The test case is rather big, and needs reducing - I'll come
 back and do that in a few days time unless anyone beats me to it (I have a
 paper deadline in 23 hours...)
