Indexing index pages is harmless, and also "nofollow" is appropriate for
public lists with lots of junk, advertising etc. We have nearly zero
spam, so following links in posts is fine.
For numbers around -67768122973228093, localtime() doesn't return in
10.6.8, while it returns NULL for 10.7.2. Work around the bug by
setting a lower bound that seems to be high enough to avoid the
problem (and that's lower than the lowest value that succeeds, so no
results are lost, at least for now).
Merge to 5.2.1
If a function with a rest arg is called with argv not at the
start of the runstack, then space is allocated for the rest-arg list
on the runstack without clearing the allocated slot. The value in
the slot could be a pointer that wasn't traversed by the most recent
GC, so it could crash a GC during allocation of the rest-arg list.
Also, tweak setup code for a function of no arguments, and improve
comments in the code.
Merge to 5.2.1
The generated code was checking arity after potentially copying
arguments to the start of the runstack (i.e., if the arguments
were not already there). If too few arguments are provided, then
the copy might access past the end of the given array.
The redundant arity check removed in commit f7c506471b
had previously masked this problem. (Or the check wasn't redundant
in that sense, but it's better this way.)

Fixed faulty bilinear interpolation in shadow intersection, removed blurring hack
Fixed caching bug (for some reason, generate-temporaries didn't create a unique symbol - note, not *identifier*; used gensym instead)
Please merge into release

For the curious, this was an attempt to change the way context
matching works. Currently, when matching a pattern, if 'hole' is
encountered, the match succeeds and the result just includes the term
at that point. This means that when matching (in-hole p1 p2), p1
generally returns multiple results and then those results are thinned
out by matching p2 against the thing actually at the hole.
Instead, one could pass along the function that does the matching and
then, when matching a hole pattern, it could decide right at that
point whether or not the match works.
This seems like it would be a win overall, but it interferes with
caching. Specifically, most reduction systems have lots of rules
that all begin
(--> (in-hole E ...) ...)
and, in the strategy first described above, that matching can be cached.
But in the second, it cannot. Overall, this turns out to be a slight
lose in the current version of Redex. Maybe if other things change, however,
this tradeoff will change.
Revert "IN PROGRESS: more context speedup attempt"
This reverts commit 0134b8753d.
Revert "IN PROGRESS: a possible speed up attempt; match the thing in the hole before returning the context matches instead of afterwards"
This reverts commit 11059e2b5c.
* The darwin build on kauai (the machine is no longer maintained, and
has no cairo installed).
* The two debian builds (also no cairo).
* Remove comment from osx64 build (which is now done on Robby's
machine).
More documentation (Now contains an animated GIF! We have achieved Web 1.0!)

The problem is related to marks that should cancel eagerly when
a form passes through many layers of macro expansion, such as in
the sieve stress test for `syntax-rules'.
