I ran into the same issue.
Here's a reduced testcase that triggers the ICE when compiled with "-flto":
=============================================
__attribute__((optimize(1))) void foo() {}
=============================================
bug.c:1:1: internal compiler error: tree code 'optimization_node' is not
supported in LTO streams
Please submit a full bug report, [etc.]
This only happens on trunk, before I get:
bug.c:1:1: sorry, unimplemented: gimple bytecode streams do not support the
optimization attribute
