I'm trying to reproduce your problem on a smaller test case (by taking snippets from the source code at http://github.com/marcomaggi/nausicaa/tree/master/uriel/libraries/uriel/lang.sls ), but so far have failed to reproduce the compiler error. Does the problem also go away if you get rid of the invocations of the defer-exceptions macro? Is there a particular invocation that the problem is strongly tied to? (I just want to confirm that this is a problem dealing with the results of expansion, as opposed to the definition of the defer-exceptions macro itself.) -Felix ___ Larceny-users mailing list Larceny-users@lists.ccs.neu.edu https://lists.ccs.neu.edu/bin/listinfo/larceny-users

If you want to follow progress on this, I filed it as ticket #600 : https://trac.ccs.neu.edu/trac/larceny/ticket/600 I will spend a bit more time trying to reduce it a bit more, but right now it seems like all of those components (the guard, the cond, the variable-arity procedure, etc) are necessary to reproduce the problem. Quite odd. As for actually fixing the problem, that may have to wait until Will gets a chance to look at it, unless I reduce it down to something really trivial to analyze... -Felix ___ Larceny-users mailing list Larceny-users@lists.ccs.neu.edu https://lists.ccs.neu.edu/bin/listinfo/larceny-users

Sorry for the whining. :) It is a bug in the compiler. You have to wait for a fix. I'll be checking one in very soon. :) -Felix p.s. people who *do* want to know why this was happening can read about it in Ticket #600.

Ticket #600 is fixed as of changeset:5880. I didn't realize that Felix was working on the problem, so I tracked it down independently. Will ___ Larceny-users mailing list Larceny-users@lists.ccs.neu.edu https://lists.ccs.neu.edu/bin/listinfo/larceny-users
