I encountered an error during compilation.

Dear developers,

Greetings! I would like to inquire about an issue I encountered while compiling Hos-ocean on Ubuntu 20.04. Could you kindly assist me in understanding the root cause of the following error?

It seems that there is an issue with the size of the allocated vectors. As a first test, you can try to force the compilation of the whole set of routines
make clean
make all
