Importing dolfin.h results in bad_alloc when trying to access eigen matrix

0 votes

I have a c++ code where in one file if I include dolfin.h, I get a seg fault as soon as I try to use an eigen matrix. Has anyone run into a problem like this before?

You are going to have to provide a (minimal) working example in order for anyone to be able to answer this...

So while I was trying to pull my code out of the rest of my project to make a minimal working example, I discovered that a local copy of Eigen was being compiled with the project. That version was 3.2.2, while the fenics library had been compiled with 3.2.92. I replaced the older version of Eigen with the newer and everything works perfectly now.
