My client has been crashing frequently (14 times today). It usually (but not always) returns me to the launcher upon crashing.

I haven't spotted a clear pattern as to when the crashes occur, though it does only seem to occur when I am interacting with the game, not while I am away from the computer.

Both the client and server are 1.7.4, both unmodded.

Crash reports from today's 14 crashes are attached.

Ready and willing to gather more data if needed!
