[chef] Segmentation fault in gecode

[AlexS < >]

I upgraded my Chef server to 0.10, and now getting segfault in gecode. Ruby
server goes down when client sends /environments/_default/cookbook_versions
request.

Server log snippet: http://pastie.org/1869858
Client log snippet: http://pastie.org/1868940

Any ideas what's happening? The system is Ubuntu 10.10, installed Gecode 3.5.0
using source tarball and manual build.
