Description

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:

["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.
