Hi, For the first part of the bug: > aermod.f90:14521: internal compiler error: in instantiate_scev_1, at > tree-scalar-evolution.c:2220 the bug was introduced by an automatic rewrite arount TREE_CODE_LENGTH http://gcc.gnu.org/viewcvs?view=rev&revision=122018 The fix avoids the gcc_assert by returning "unknown scalar evolution". The second part of the bug was already fixed: > aermod.f90:8312: internal compiler error: in expand_scalar_variables_expr, at > graphite.c:3168 I will apply the patch below once it finishes regstrap.
