#1719: unbounded growth from parameterize
---------------------------------+-----------------------------------------
            Reporter:  Jim Rees  |       Type:  defect
              Status:  new       |   Priority:  minor
           Milestone:  someday   |  Component:  core libraries
             Version:  5.2.0     |   Keywords:  make-parameter parameterize
Estimated difficulty:            |
---------------------------------+-----------------------------------------
 I know of no practical use case for an unbounded number of created and
 forgotten parameter objects, so assign the appropriate level of priority
 to this -- I just thought it was an interesting case.  I recently realized
 this was possible on my own toy scheme and fixed it by switching to
 ephemerons in my continuation-marks cell representation.   chibi, mit-
 scheme, chez, guile, gauche -- all have unbounded growth on this test as
 well.

 #;1> (let loop () (parameterize (((make-parameter #f) (make-vector
 10000))) (loop)))
 [panic] out of memory - heap has reached its maximum size - execution
 terminated
