I've attached new reduced test case for the error. Getting same error ... gfortran -c -O3 -floop-block updated_protein.f90 updated_protein.f90: In function 'superficie_proteina': updated_protein.f90:1: error: type mismatch between an SSA_NAME and its symbol updated_protein.f90:1: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
