Through trial and error I have managed to trim a test case down to around 200 lines of code. A ";;gap" comment means I have cut out a piece of code. A ";;keep form" comment just means I tried to cut the form out but a VerifyError went away. The test case is attached as psyntax.temp. It's annoying that Scheme doesn't allow a body with no expressions in lambdas and lets like Common Lisp does. I had to keep pasting in expressions just to satisfy the compiler (hence the form (write "Hi Per!")). This is the error message psyntax.temp currently generates: (load "psyntax.temp") java.lang.VerifyError: (class: atInteractiveLevel, method: lambda1topIdBoundVarName426 signature: (Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object;) Bad type in putfield/putstatic at java.lang.Class.getDeclaredFields0(Native Method) at java.lang.Class.privateGetDeclaredFields(Class.java:1514) at java.lang.Class.getDeclaredField(Class.java:1206) at gnu.expr.ModuleExp.evalToClass(ModuleExp.java:116) at gnu.expr.ModuleExp.evalModule(ModuleExp.java:169) at kawa.Shell.run(Shell.java:233) at kawa.standard.load.loadSource(load.java:161) at kawa.standard.load.apply(load.java:273) at kawa.standard.load.apply2(load.java:199) at kawa.standard.load.apply1(load.java:189) at gnu.mapping.Procedure1.applyN(Procedure1.java:49) at gnu.mapping.Procedure.apply(Procedure.java:115) at gnu.mapping.CallContext.runUntilDone(CallContext.java:289) at gnu.expr.ModuleExp.evalModule(ModuleExp.java:191) at kawa.Shell.run(Shell.java:233) at kawa.Shell.run(Shell.java:180) at kawa.Shell.run(Shell.java:167) at kawa.Shell.run(Shell.java:154) at kawa.repl.main(repl.java:650) Regards, Adam
