[plt-scheme] require: broken compiled code (phase 0): cannot find module |,X:\ants\geometry| in: sensed-cell

First of all, it was indeed a stupid error.
Second, I forgot to mention that error also happens on Check Syntax.
Third, I have reproduced the problem in smaller scale with test-a.ss and
test-b.ss:

(module test-a mzscheme
  b
  (require "test-b.ss"))

(module test-b mzscheme
  (define b "Hello, world!\n")
  (provide b))

[Error-message: require: broken compiled code (phase 0): cannot find =
module
|,u:\test-b| in: b]

This does not happen if I change test-a.ss to

(module test-a mzscheme
  (display b)
  (require "test-b.ss"))

Or to

(module test-a mzscheme
  (require "test-b.ss")
  b)

But does happen with

(module test-a mzscheme
  (newline)
  b
  (require "test-b.ss"))

Any idea why using an identifier by itself would cause a different
behaviour? The last module was tested to make sure that it's not using =
it as
some sort of weird third-parameter to "module" (as in (module a b c
(code))).

ifconfig.

Well, for one thing, you forgot to "(provide b)" in module d.  That=20
would account for the error you got.  Fixing this makes the error go=20
away:

(module d mzscheme
   (provide b)
   (define b 14))

(module c mzscheme
   (printf "value of b: ~v\n" b)
   (require d))

(require c)

=3D=3D>
value of b: 14



Don't know what causes the error you reported, though.
