[gambit-list] Bug involving syntax-rules and c-lambda

Hi there,
I decided that it would be good to make sure that I am up-to-date with
Gambit 4.4 before I posted my web framework here for those who have
expressed an interest and I am finding a destructive interaction when using
the c-lambda form.
With the code in the sequel and Gambit 4.4.0, if I compile thusly:
$ gsc -:s -link bug.gambit
*** ERROR IN MAP -- invalid syntax ()
but it compiles fine if I omit the -:s option. Now obviously, the example
does not require syntax-rules macros, but the full framework certainly does.
Is there a known incompatibility here? The text concerning define-syntax
hints at such a possibility, but the actual interaction is unclear.
