xmlFreeChars error (on Windows)

[cyphic]

Hi,

when I got a call like that:

imgnode.Attr("src")

or

imgnode.Attribute("src").Value()

I get the following error:

unexpected fault address 0x137425ff
throw: fault
[signal 0xc0000005 code=0x0 addr=0x137425ff pc=0x137425ff]

goroutine 1 [syscall]:

similar errors also happen when running the tests in : go test github.com/moovweb/gokogiri/xml

the only way to access the attributes right now, seems to be doing something like:

var attribute string
attribute = string((*imgnode.Attribute("src")).ToBuffer(nil))
attribute = strings.Trim(attribute[strings.Index(attribute, "=")+1:], "\"' ")

What's your libxml version?

[cyphic]

I compiled the source code of libxml2-2.7.8, as gokogiri wouldn't install with the downloadable precompiled libs (something to do with msvc vs. mingw gcc compiler incompatibility according to some search results ...

also, as a windows user, there isn't really support for pkg-config, so I had to to improvise a .pc file from information i could find on how it works ... so its quite probable, i messed some part of it up

so if you or someone else could provide a fully working installation "step by step" for gokogiri for windows users, not just I would be thankful (it took me about 5 hours to get it installed).

Hey @cyphic, someone recently made steps on getting gokogiri work for windows:

https://github.com/moovweb/gokogiri/issues/49

Does that help out at all?
