Illegal instruction at kalibr_calibrate_imu_camera on the sample dataset

[shprotello]

I've installed Kalibr tool for evaluation. Camera calibration step passes OK, but at kalibr_calibrate_imu_camera call I get Illegal instruction signal even on the sample dataset.
Is there anybody know what is wrong with it?

• OS: Ubuntu 16.04
• Kalibr: built from sources
• Command from the sample dataset:
  kalibr_calibrate_imu_camera --target april_6x6.yaml --cam camchain.yaml --imu imu_adis16448.yaml --bag dynamic.bag --bag-from-to 5 45
• Output (fragment):

    `...
     Initializing a pose spline with 4004 knots (100.000000 knots per second over 40.040000 seconds)
     Initializing the bias splines with 2002 knots
     Adding camera error terms (/cam0/image_raw)
     Illegal instruction (core dumped)`

Thank you!

Did you remember how (or if) you solved this issue? I am also seeing Illegal instruction (core dumped) on kalibr_calibrate_rs_cameras. I'm not seeing a stack trace though.
