Details:

Syntax definitions (using define-syntax) that are loaded into the current
environment from compiled scheme classes with require (or programmatically
with loadClass) cause an "unbound location exception" when they expand to
calls to functions defined in the same scope as the syntax definition. The
problem only occurs when the function that is called by the syntax refers to
other defined values. For example, in the attached testcase, replacing the
identifier foobar with the string "foobar" fixes the problem.

I have attached two scheme files that make up a testcase for this problem. To
reproduce the problem, compile brokensyntax.scm (kawa -C) and then run
brokensyntax-test.scm (kawa -f). I haven't had time yet to figure out a fix
for this problem. I have tested this against r5524.
