Yibo Cai created ARROW-7397: ------------------------------- Summary: [C++] Json white space length detection error Key: ARROW-7397 URL: https://issues.apache.org/jira/browse/ARROW-7397 Project: Apache Arrow Issue Type: Bug Components: C++ Reporter: Yibo Cai
Commit 21ca13a5cd [1] introduces a bug in ConsumeWhitespace() function. When all chars in a string are white spaces, it should return string length. But current code returns 0. It's not noticed because x86 goes rapidjson simd code path which is okay. Arm64 now goes the buggy code path and triggers json unit test failure.
