Segfault in JSON - windows VISTA

Ruby
1

I’ve been struggling for the past few hours with a segfault coming out
of JSON.

this is from the gem “json (1.1.1)” and “json (1.0.3)”

I was originally running the ruby 1.8.6 one-click-installer,
but reverted to 1.8.4 a moment ago, to see if it fixed the problem.

I’ve also tried varying the version of the JSON gem.

hmm…I can’t see how to fix this.
any ideas.

I guess maybe I should just revert back to WinXP,
it was working in 1.8.4 on XP MCE

I correct myself,
that was with json 1.0.3.

btw, I’m running this from command prompt - running it “as
administrator”

ok I’ve managed to get it to work by using the “json_pure” gem instead.
but it’s annoying
