Description Akira TAGOH 2017-02-07 13:40:55 UTC
Description of problem:
mozc doesn't support the big endian architectures at this moment. so it has to have ExcludeArch: ppc ppc64.

Comment 1 Mamoru TASAKA 2017-06-19 06:11:45 UTC
From https://koji.fedoraproject.org/koji/taskinfo?taskID=20011859 , the failing part is not char array subscript issue but:


[659/811] cd ../../rewriter; ../out_linux/Release/gen_usage_rewriter_dictionary_main "--usage_data_file=../third_party/japanese_usage_dictionary/usage_dict.txt" "--cforms_file=../data/rules/cforms.def" "--output_base_conjugation_suffix=../out_linux/Release/gen/rewriter/usage_base_conj_suffix.data" "--output_conjugation_suffix=../out_linux/Release/gen/rewriter/usage_conj_suffix.data" "--output_conjugation_index=../out_linux/Release/gen/rewriter/usage_conj_index.data" "--output_usage_item_array=../out_linux/Release/gen/rewriter/usage_item_array.data" "--output_string_array=../out_linux/Release/gen/rewriter/usage_string_array.data"

And ./rewriter/gen_usage_rewriter_dictionary_main.cc has a comment:

The line 251 has;
   250  void Convert() {
   251    CHECK(Util::IsLittleEndian());

Right. so reverted the change and added s390x to ExcludeArch then.
