Crash in ruby 1.8.0

[Brett H. Williams]

This doesn't look right...

vor-lord:scan_plan/scan_plan> ruby -e 'def next(); end; next()'
-e:1: [BUG] Segmentation fault
ruby 1.8.0 (2003-08-04) [i386-linux]

Aborted

I thought I could create a method with a name that matched a reserved word
as long as I was careful how it was called (like Object#class). At the
least I would've expected that I would get an error telling me not to
define a method called "next". But a segmentation fault seems to be the
wrong result no matter what...

It crashes on HPUX also, however on my old 1.7.3 version it gives me the
unexpected next error.

Actually:

rpav@central:~% ruby -e 'next()'
-e:1: [BUG] Segmentation fault
ruby 1.8.0 (2003-08-04) [i686-linux]

Weird.

Hi all,
I'm pretty new to Ruby, and I came across the Ruby bindings
(http://pablotron.org/software/mb-ruby/) to the musicbrainz project
(musicbrainz.org).

I'd like to use Ruby to generate acoustic fingerprints when fed an MP3
file. Reading over the API, I see this method that looks like it will
do what I want:

/*
* Pass raw PCM data to generate a signature.
*
* Note: MusicBrainz::TRM#pcm_data must be called before this
function.
*
* Returns true if enough data has been sent to generate a signature,
* and false if more data is needed.
*
* Example:
* trm.generate_signature buf, BUFSIZ
*
*/
static VALUE mb_trm_gen_sig(VALUE self, VALUE buf) {


However, I'm not sure how I'd go about passing raw PCM data to Ruby.
Any suggestions? I posted this on comp.lang.ruby too (although it
hasn't shown up yet), I hope no one's offended about the double post if
you frequent both places.

Thanks alot!

Well, the variable buf is just a String object and you call it :

trm.generate_signature(string)

this is equivalent to the C function trm_GenerateSignature()
