Segmentation fault (core dumped) occurs when run test_pipeline

[chenchr]

a few days before i run the test_pipeline correctly, today, i pull the latest version of svo, compile and run test_pipe, it show that :
[INFO] SVO initialized
reading image /home/chenchr/Datasets/sin2_tex2_h1_v8_d/img/frame_000002_0.png
[INFO] RESET
[INFO] Init: Selected first frame.
Frame-Id: 0 #Features: 0 Proc. Time: 6.229ms

[INFO] Init: KLT tracked 543 features
[INFO] Init: KLT 50.8035px average disparity.
Segmentation fault (core dumped)

then i use cout to locate where the error happens, when invokes processSecondFrame, it invokes KltHomographyInit::addSecondFrame, and then it will invoke
computeHomography, it set up the cout(means that i cout some text to remind me the program works) before that, which go fine. then i set up a cout at the
end of function computeHomography, it works too. however, i set up the cout in KltHomographyInit::addSecondFrame just after the function computeHomography
the error "Segmentation fault (core dumped)" occurs again, i think the reason of error maybe have something to do with the function arguments. however i can't fix it. can anyone help me out ?
thanks!

i recompile vikit and then svo, it works.

I also meet same problem.But no matter how i recompile vikit and svo,it did not work.

I also meet this problem. Due to the bt output, I think there may be some problems with this function vk::Homography::decompose(). Anyone has ideas?

After I recompile vikit without -march=nactive, it works Haha.

[Tsugikuni-Yoriichi]

Same problem. Again and again. As @Beniko95J suggested, problem changes. I pasted last three rows of problem. After move -march=nactive, problem changes from (1) to (2).
(1)
[INFO] Init: Selected second frame, triangulated initial map.

(2)

[xixi0226]

delete the sentence about "-march " in CMakeLists.txt

[yizhang-group]

yes, as @xixi0226 and @Beniko95J said, delete "-march" in svo and vikit, and then recompile them.
