Tobias Burnus <burnus at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |burnus at gcc dot gnu.org --- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> --- Created attachment 30565 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30565&action=edit Patch to make it compile with GCC 4.8 and 4.9 (In reply to shapero from comment #0) > git clone https://github.com/danshapero/fempack.git > git checkout e7547abe131b5c0e137fb0327069a75fcfed5d90 > make libs To underline the elusiveness: With 4.7.3 (release build), it builds without running into the ICE. With GCC 4.9 (and GCC 4.8) it doesn't build: src/linalg/matrix_formats/csr.f90:24.13: procedure :: subset_matrix_add => csr_subset_matrix_add 1 Error: Argument mismatch for the overriding procedure 'subset_matrix_add' at (1): Type mismatch in argument 'b' (CLASS(csr_matrix)/CLASS(sparse_matrix)) However, if I apply the attached patch, it builds with gcc 4.9 - and I can reproduce the "free_pi_tree(): Unresolved fixup".
