Subject: tabs and parse errors with Ruby 1.8.4 and Windows

This is a cross-post from the Rails list in hopes of getting some 
information from people who know more about the Ruby side of things.

I get compile errors from ERB in my Rails views when I load the ferret C 
extension. Apparently this also happens with RMagick. The most common 
response I've seen is to replace all tabs with spaces, and the problem 
will go away. I would like to know why that works, what the problem is, 
and if there's anything I can do to fix it. Making sure none of my views 
contain tab characters is not a solution I'm comfortable with for a 
production environment. This is what the errors look like:

compile error
./script/../config/../app/views/search/query.rhtml:5: Invalid char
`\002' in expression
./script/../config/../app/views/search/query.rhtml:6: parse error,
unexpected tIDENTIFIER, expecting kEND
_erbout.concat "		<strong>"xP; _erbout.concat(( "%d%%" % (result.RANK /
1000.0 * 100) ).to_s); _erbout.concat "</strong>\n"
                		           ^
./script/../config/../app/views/search/query.rhtml:7: parse error,
unexpected $, expecting kEND

I have tried recompiling everything (Ruby, extensions, zlib, and ferret) 
myself, and only using the precompiled binaries for readline.dll and 
iconv.dll because I can't find the source for the Windows ports 
anywhere. That made no difference, so I was thinking it was a Ruby bug 
(since it happened with two different extensions), but I guess it could 
be something odd both extensions are doing, too. Other people reporting 
this problem have indicated it started with Ruby 1.8.4.

See the Rails thread for more details:
