Bad logging when the javascript view server crashes
---------------------------------------------------
Key: COUCHDB-1169
URL: https://issues.apache.org/jira/browse/COUCHDB-1169
Project: CouchDB
Issue Type: Bug
Components: JavaScript View Server
Affects Versions: 1.0.2
Environment: Fedora 15
Reporter: Thomas Vander Stichele
I've been trying to rebuild my 1.0.x branch on Fedora 15. I have applied all
patches from the Fedora RPM, which among other things fixes the update to libjs.
Now my view server terminates when I query a view:

This gives no clue whatsoever as to what is failing. After reading the code
and some painful debugging, I was able to reproduce at least some kind of
problem by hand:
[thomas@level 1.0.x]$

["error","unnamed_error","(new TypeError(\"State.funs is undefined\",
\"/home/thomas/dev/ext/couchdb/branches/1.0.x/share/server/main.js\", 1311))"]
However, it keeps running. IIRC 139 means that the program got SIGSEGV ?
I'll try and replay all the requests to see if I can reproduce.
