lto1: internal compiler error: in operator[], at vec.h:736
0xffc277 vec<tree_node*, va_heap, vl_embed>::operator[](unsigned int)
../../gcc/gcc/vec.h:736
0xffd678 vec<tree_node*, va_heap, vl_embed>::operator[](unsigned int)
../../gcc/gcc/vec.h:1184
0xffd678 vec<tree_node*, va_heap, vl_ptr>::operator[](unsigned int)

0xffd678 ipa_value_from_jfunc(ipa_node_params*, ipa_jump_func*)
../../gcc/gcc/ipa-cp.c:937
The out of range access here is caused by pass through function specifying an
index of function parameter that is past the end of ipa-cp lattice.
I suppose it is either some kind of datastructure corruption or a fact that we
manage to inline function call with mismatching arguments?
I saw ICE on this spot in the past and they usually were the first - we forgot
to update correctly after inlining...
What is your -march=native?
