--- Comment #8 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > Fixed on trunk. Closing When compiling the original test, the ICE is gone but I get: Undefined symbols for architecture x86_64: "_idxs.3783", referenced from: ___sparse_matrix_csx_benchmark_utils_MOD_sparse_matrix_csc_benchmark in ccP98FL2.o "_idxs.3792", referenced from: ___sparse_matrix_csx_benchmark_utils_MOD_sparse_matrix_csr_benchmark in ccP98FL2.o This looks weird.
