--- Comment #5 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-06-09 22:22:39 UTC --- The following should partially helps: It solves the segfault for z(:) = [ x, y ] and does a deep copy. TODO: - I miss a freeing of the components of the LHS, there is currently just a malloc, cf. - Realloc on assign does not work properly: * Valgrind shows: "Conditional jump or move depends on uninitialised value" * Values print Ok, but afterwards it segfaults - with reshape, the values are still wrong. --- a/gcc/fortran/trans-expr.c +++ b/gcc/fortran/trans-expr.c @@ -5347,6 +5347,9 @@ gfc_trans_scalar_assign (gfc_se * lse, gfc_se * rse, gfc_typespec ts, tmp); gfc_add_expr_to_block (&block, tmp); } + else + gfc_add_expr_to_block (&block,gfc_copy_alloc_comp (ts.u.derived, + rse->expr, lse->expr, 0)); } else if (ts.type == BT_DERIVED || ts.type == BT_CLASS) {
