Dear all,

I complied opencv 2.4.13 on Ubuntu14.04(gcc 4.8.2 ), and it FAILED when I ran the accuracy test opencv_test_calib3d . The exact failed test was fisheyeTest.rectify.

I thought it failed because the source and the testdata were different versions. So I downloaded testdata 2.4.13 releases from github ,but it didn't work.


Then, I rebuilded opencv on VS2015(win10), the fisheyeTest.rectify passed.

Why ubuntu's fisheyeTest.rectify failed but win10 passed with same source and same testdata? Why different behaves between ubuntu and win10?

I have tried gcc 5.4.0 on ubuntu 16.04, but failed again.

Thanks for your help.
