Julia 0.6.1 throws StackOverflowError when code is called inside a loop

[KenziTrader]

Code inside gist.

Calling update!(ahrs, gyro*pi/180., accel) inside a loop causes a StackOverflowError, outside not. The problem is in line 27, building the Matrix J. Building it in rows doesn't cause the error.

Actually crashes internally on somewhat older master: Version 0.7.0-DEV.1271:
