unmodified source
no deviations from the standard procedure for installing Guile
here's a snippet that demonstrates the behavior I'm wondering about:
(use-modules (ice-9 threads))
(use-modules (ice-9 format))
(for-each
(lambda (sym)
(make-thread
(lambda ()
(display (format #f "Hey you: ~A~%" sym))
)))
(list 'bob 'sam))
Invoke the snippet with `guile -s snippet.scm'. Note the total lack
of output.
Compare this to what happens if you comment out `(use-modules (ice-9
format))', thus presumably bringing in a different `format' procedure:
you see output as I'd expect, namely
Hey you: bob
Hey you: sam
Also compare this to what happens if you eliminate the call to
`make-thread', like this:
(use-modules (ice-9 format))
(for-each
(lambda (sym)
(display (format #f "Hey you: ~A~%" sym)))
(list 'bob 'sam))
This, too, produces the output shown above.
The bug, or at least my confusion, is that the first version produces
no output.
