Yes, PR#3640 is an AMD64-specific code generation bug.  It occurs in
the uncommon case where a leaf function (a function that doesn't call
other functions except as a tail-call) accesses a parameter passed on
the stack (not in registers).  As a rule of thumb, if your tail
functions have fewer than 9 arguments, you're safe.

The bug is fixed in the CVS repository, 3.08 bug-fix branch.
