[Message part 2 (message/rfc822, inline)]
[Message part 3 (text/plain, inline)]
Proc ‘uniform-vector-read!’ is deprecated (ugh), and its implementation
rebased onto ‘(rnrs io ports) get-bytevector-n!’. Unfortunately, there
seems to be a glitch in the arg shuffling. Here is /tmp/foo.scm:
[foo.scm (application/x-scheme, attachment)]
[Message part 5 (text/plain, inline)]
and here is a series of invocations that demonstrate the discrepency
between ‘get-bytevector-n!’ (ok) and ‘uniform-vector-read!’ (ko):
[badness (text/plain, inline)]
set -x ; guile --version ; guile -s foo.scm ; guile -s foo.scm ok ; guile -s foo.scm ko
+ guile --version

`uniform-vector-read!' is deprecated. Use `get-bytevector-n!' from
`(rnrs io ports)' instead.

FWIW, Guile 1.8.8 produces same output as ‘ok’ on a similar (sans the
‘use-modules’ and ‘uniform-vector-element-size’ noise) input, so i think
this situation is a regression. Am i missing something?

As long as it wasn't _next_ release, I am happy to fix it.
Patch pushed. Closing.
