Hello, We have a plugin that writes both Arrow and Parquet format files. We are experiencing an issue when using Parquet format, while Arrow format works just fine. More exactly, the process crashes in parquet::arrow::WriteTable.
Using gdb we identified the line when the process crashes https://github.com/Paradigm4/bridge/blob/8c34f3b940b10a38eb8900cd05d7ee6aa7c082b0/src/PhysicalXSave.cpp#L494 The gdb output is: (gdb) catch syscall exit_group Catchpoint 1 (syscall 'exit_group' [231]) (gdb) c Continuing.
