compile exhausts heap but load does not

[andy arvid]

I have run into a situation where loading a file works but compiling the same file causes heap exhaust.
I originally found this writing tests using the "prove" library ( https://github.com/fukamachi/prove
).
In particular, using deftest about 1000 times in a file.
Basically each deftest consumes 1+MB of memory but during loading the GC recovers a lot of it where as during compiling the GC recovers very little.

I created a test project called prove-fail https://github.com/aarvid/prove-fail
to demonstrate the error. And I created an issue here: https://github.com/fukamachi/prove/issues/25.

I since tried to eliminate the prove library and have created a test project here:
https://github.com/aarvid/comp-heap-exhaust

This does not depend on prove but emulates it.

This repository also contains log files of the slime REPL and inferior lisp. for both 1.3.3 and the developmental version.
