thread support changes the ABI; to verify this is
indeed the problem, try texmacs together with guile-1.8 1.8.2+1-1 - if
I'm correct, that should fix the segfault. Then just rebuild with the
latest guile-1.8 to fix the problem.

Hi!
Here's a few patches related to R6RS port support, in short:
- Add missing `get-string-n!' and `get-string-n'
- Fix a few missing exports
- A bit of work on transcoder-related stuff
Attached is an updated version of the rnrs-transcoders patch

In porting dorodango[0], I have noticed that Guile's R6RS fixnum
operations are quite slow; here's a patch to remedy that a bit. The
patch contains a benchmark for `fxxor', which experiences a performance
improvement of 2 with the patch.
[0] http://home.gna.org/dorodango/
I also used real code
* module/rnrs/arithmetic/fixnums.scm (assert-fixnum): Is now a
macro.
(assert-fixnums): New procedure checking a the elements of a list
for fixnum-ness. All callers applying `assert-fixnum' to a list
now changed to use this procedure.
* module/rnrs/arithmetic/fixnums.scm (define-fxop*):
This primitive can be used to significantly speed up the operations in
`(rnrs arithmetic fixnums)'.
* libguile/numbers.c (scm_fixnum_p): New predicate.
* libguile/numbers.h: Add prototype.
* libguile/vm-i-scheme.c (fixnump): New VM primitive; renumbered
subsequent operations.
*
This is another piece of my attempt at getting more speed out of the
`(rnrs arithmetic fixnums)' library. The idea is that this patch would
be applied to master. I think, at least in the current form, it is not
eligible for 2.0.x, as it messes up the VM opcode numbers, which breaks
all .go files,
along, so don't hold your breath ;-).
