543	(declare (lambda-lift)) infinite loop.	Alan Post	felix winkelmann	"I have done some refactoring to my package genturfa'i.  After completing my refactoring, the lambda-lift option now never terminates while compiling genturfa'i.

To recreate this problem:

{{{
svn co -r23157 https://code.call-cc.org/svn/chicken-eggs/release/4/genturfahi/trunk
cd trunk
chicken-install
}}}

The problem is occurring in the function compute-extra-variables in optimizer.scm.  I narrowed this down using the verbose option to the compiler invoked by chicken-install, but attempts on my part to provide a simpler test case have failed.

Turning off (declare (lambda-lift)) causes genturfa'i to compile normally.  I would expect to be able to compile my module with lambda lifting, rather than having in never terminate."	defect	closed	critical	4.9.0	compiler	4.6.x	fixed
