rack showexceptions.rb 46 BUG rb gc mark unknown data type 0x10 0xb7ec8198 non object

February 24th, 2010

Hmmmm. Is this it?

I seem to be having a ton of problems with segmentation faults lately. What gives?

sudo gem install rcov

Updating rcov seems to have helped a little, and some further spelunking reveals that my test cases needed some updates.

Still:

/var/lib/gems/1.8/gems/dm-core-0.10.2/lib/dm-core/model.rb:490: [BUG] Segmentation fault
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

Doh!

I'd really like to get to the bottom of this. Better yet, I'd really like to make the full switch from Ruby 1.8 to 1.9.

I think I'm using something that can't use 1.9 yet. Puppet? Maybe. Well I'm going for it anyway.

I'll try reinstalling these packages as gems instead, but first I need to install rubygems1.9!

apt-get install rubygems1.9 ruby1.9-dev

Grrr... why are these different than 1.9.1?
