Description

Eric Marsten reports in ​http://article.gmane.org/gmane.lisp.armedbear.devel/2611:

The following illustrates what looks like a bug in the compiler's
handling of type propagation (bug disappears without the type
declaration).

CL-USER(25): (lisp-implementation-version)
"1.1.0-dev-svn-14222M"
"OpenJDK_64-Bit_Server_VM-Oracle_Corporation-1.7.0_03-b21)"
"amd64-Linux-3.3.0-trunk-amd64)"
CL-USER(26): (defun foo (a b)
              (declare (type (integer * 6488318769) b))
              (max 1 (the (integer * 5711538578) a) b 2 1351352470))
