Segmentation fault when executing just after compiling

Hello. I am trying to install the game from source but it does not work. I already had a few compilation errors which I managed to solve, due to changes in the ImGui repository (I have already requested those changes to be merged). However when I run ./anura --modules=citadel I get the following log:

Also a segmentation fault at the end. When executing with valgrind it gives the following additional information:

All the dependencies where satisfied and the compilation and linking processes end with no errors.

I cannot find any call to ImGui::CreateContext() in the code. I suppose the ImGui context used to be set with a different function in previous versions so I must change that to the new one, but I am unable to find it.

I want to contribute to the game, so I would be thankful for any help you can give me.

NOTE: I thought I might have downloaded the wrong version of ImGui, but even if I download the version linked in the anura engine repository it updates during the compilation. I guess that was the problem all the time but I do not know how to disable it.
