Dear developers of clipper,
I am trying to implement clipper into my ros1 cpp project (see the simple test code i posted). I copied it directly from your unit test script and this error keeps showing up:

The eigen version i used to compile clipper is 3.3.7 and system ubuntu 20. I really appreciate your kind reply. Please let me know if anything else i can provide from my side.
Regards Shuoyuan
Hi, does it work when you run the tests directly from the clipper repo? i.e., following the build steps in the README
it may be that eigen 3.4.x is required
OK this is more complicated than i thought it would be, i cant replicated it everytime. When i run ./tests executable, it fails 9/10 times, yet when i run ctest --output-on-failure -j$(nproc) it is almost always correct. When I run ./tests --gtest_filter=CLIPPER.EuclideanDistance alone it works 9/10 times.

I tried 3.4 and similiar issue still persist with your tests. As for my code, same double free or corruption issue after updating eigen to 3.4. Here is the simpliest version of my code if you need to test it:
