ruby -v: ruby 1.9.1p243 (2009-07-16 revision 24175) [x86_64-linux]

Ruby 1.9.1 segfaults when calling ActiveRecord::Base.transaction, dump attached (that's what the line with the error does). 

Testcase is very repeatable (happens every time I run my specs), but slightly non-deterministic: changing a few lines of code will change in which particular test it happens (multiple tests go through the same code-path, doesn't always happen every time you go through the same path), and though it is usually in the same spot in the code it has sometimes happened in other spots (deeper within the same call-chain). 

Unfortunately the code is for a commercial project and I can't share it. Sorry. I can work with someone from the ruby-core community to e.g. run debug versions of ruby on the test case if that is of use. 


Environment: 

- Ubuntu 9.04 on a basic intel box
- Rails 2.3.4
- DB: PostgreSQL, with ruby-pg binding
