While I was trying to build gcc with -fno-fat-lto-objects I hit this ICE:

../../../../gcc/libstdc++-v3/src/complex_io.cc:92:1: internal compiler error:
in produce_symtab, at lto-streamer-out.c:1435

Reduced testcase is attached.

 % g++ -fno-implicit-templates -w -fpermissive -flto test.ii
test.ii:108:23: internal compiler error: in produce_symtab, at
