I will email all the .go files under .../rpc/api. root@linux05:~/Downloads/go-ethereum# make geth build/env.sh go install -x -v -ldflags '-X main.gitCommit 4813a39100dc8dc884b0a68ceae51c2c420f92af' ./cmd/geth WORK=/tmp/go-build873382851 github.com/ethereum/go-ethereum/rpc/api mkdir -p $WORK/github.com/ethereum/go-ethereum/rpc/api/_obj/ mkdir -p $WORK/github.com/ethereum/go-ethereum/rpc/ cd /root/Downloads/go-ethereum/build/_workspace/src/github.com/ethereum/go-ethereum/rpc/api /usr/bin/gccgo-5 -I $WORK -I /root/Downloads/go-ethereum/build/_workspace/src/github.com/ethereum/go-ethereum/Godeps/_workspace/pkg/gccgo_linux_s390x -I /root/Downloads/go-ethereum/build/_workspace/pkg/gccgo_linux_s390x -c -g -fgo-pkgpath=github.com/ethereum/go-ethereum/rpc/api -fgo-relative-import-path=_/root/Downloads/go-ethereum/build/_workspace/src/github.com/ethereum/go-ethereum/rpc/api -o $WORK/github.com/ethereum/go-ethereum/rpc/api/_obj/_go_.o ./admin.go ./admin_args.go ./admin_js.go ./api.go ./args.go ./db.go ./db_args.go ./db_js.go ./debug.go ./debug_args.go ./debug_js.go ./eth.go ./eth_args.go ./eth_js.go ./mergedapi.go ./miner.go ./miner_args.go ./miner_js.go ./net.go ./net_js.go ./parsing.go ./personal.go ./personal_args.go ./personal_js.go ./shh.go ./shh_args.go ./shh_js.go ./txpool.go ./txpool_js.go ./utils.go ./web3.go ./web3_args.go # github.com/ethereum/go-ethereum/rpc/api go1: internal compiler error: in write_specific_type_functions, at go/gofrontend/types.cc:1812 0x802473df Type::write_specific_type_functions(Gogo*, Named_type*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, Function_type*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, Function_type*) ../../src/gcc/go/gofrontend/types.cc:1812 0x80245b33 Type::specific_type_functions(Gogo*, Named_type*, Function_type*, Function_type*, Named_object**, Named_object**) ../../src/gcc/go/gofrontend/types.cc:1791 0x8024639d Type::type_functions(Gogo*, Named_type*, Function_type*, Function_type*, Named_object**, Named_object**) ../../src/gcc/go/gofrontend/types.cc:1668 0x8024eff7 Type::type_descriptor_constructor(Gogo*, int, Named_type*, Methods const*, bool) ../../src/gcc/go/gofrontend/types.cc:2011 0x80250b1d Array_type::array_type_descriptor(Gogo*, Named_type*) ../../src/gcc/go/gofrontend/types.cc:6318 0x80248a33 Type::make_type_descriptor_var(Gogo*) ../../src/gcc/go/gofrontend/types.cc:1218 0x80248e05 Type::type_descriptor_pointer(Gogo*, Location) ../../src/gcc/go/gofrontend/types.cc:1156 0x801c8e6f Type_descriptor_expression::do_get_backend(Translate_context*) ../../src/gcc/go/gofrontend/expressions.cc:13400 0x801a8efd Interface_value_expression::do_get_backend(Translate_context*) ../../src/gcc/go/gofrontend/expressions.cc:14023 0x8021ef49 Temporary_statement::do_get_backend(Translate_context*) ../../src/gcc/go/gofrontend/statements.cc:470 0x801e8d27 Block::get_backend(Translate_context*) ../../src/gcc/go/gofrontend/gogo.cc:5811 0x8021ea51 Block_statement::do_get_backend(Translate_context*) ../../src/gcc/go/gofrontend/statements.cc:1802 0x801e8d27 Block::get_backend(Translate_context*) ../../src/gcc/go/gofrontend/gogo.cc:5811 0x8021ea51 Block_statement::do_get_backend(Translate_context*) ../../src/gcc/go/gofrontend/statements.cc:1802 0x801e8d27 Block::get_backend(Translate_context*) ../../src/gcc/go/gofrontend/gogo.cc:5811 0x801ea647 Function::build(Gogo*, Named_object*) ../../src/gcc/go/gofrontend/gogo.cc:5417 0x801ebd7d Named_object::get_backend(Gogo*, std::vector<Bexpression*, std::allocator<Bexpression*> >&, std::vector<Btype*, std::allocator<Btype*> >&, std::vector<Bfunction*, std::allocator<Bfunction*> >&) ../../src/gcc/go/gofrontend/gogo.cc:7136 0x801f514d Gogo::write_globals() ../../src/gcc/go/gofrontend/gogo.cc:1345 Please submit a full bug report, with preprocessed source if appropriate.
