I added some println statements to see if maybe the db connection was null or if the statement length wasn't right. Nothing obvious is coming up. This is the query that is breaking. When I execute it from the sqlite CLI it returns nothing.
path="/home/ubuntu/test/test1" mtime=1479232483 nsec=800923063 size=0
db: 0x7fcdaad82008
len_with_nul: 84
sql: SELECT blocks FROM mtime_cache WHERE path=? AND mtime=? AND mtime_nsec=? AND size=?

Do you know which version of SQLite you are using (the one rusqlite is linked to) ?
You can call println!("{:?}", libsqlite3_sys::sqlite3_version) or SELECT sqlite_version().
Thanks.

I believe it's this:
ii libsqlite3-0:amd64 3.11.0-1ubuntu1 amd64 SQLite 3 shared library
ii libsqlite3-0-dbg 3.11.0-1ubuntu1 amd64 SQLite 3 debugging symbols
ii libsqlite3-dev:amd64 3.11.0-1ubuntu1 amd64 SQLite 3 development files

Why pWC->a is null (sqlite3.c:123127) ?
Maybe an allocation problem in whereClauseInsert ?

I'm not sure if the problem is my FFI Ceph bindings I created or the sqlite bindings. Yeah the pWC->a null is very strange. It could be that my bindings are messing something up and sqlite is blowing up because of it or maybe my stuff isn't related. I can't tell yet.

Ok we can close this issue. I tracked it down with valgrind. My library was using some bogus pointers and it was causing sqlite to blow up. There's no problem with the sqlite library :)
