Alexey Serbin created KUDU-3479:
-----------------------------------
Summary: codegen is broken if compiled with GCC11 and newer
Key: KUDU-3479
URL: https://issues.apache.org/jira/browse/KUDU-3479
Project: Kudu
Issue Type: Bug
Components: codegen
Affects Versions: 1.17.0
Reporter: Alexey Serbin
When compiled with GCC11 and newer, Kudu masters and tablet servers are
crashing. The stack trace of {{kudu-master}} looks like the following:

The litmus test is to run {{codegen-test}} that is crashing with similar stack:

{noformat}
Workaround is to disable the codegen when running {{kudu-master}} and
{{kudu-tserver}} processes:
{noformat}
--mrs_use_codegen=false
{noformat}
Fixing this issue should unblock Kudu adoption on contemporary Linux
distributions where GCC11 or newer is a system compiler (RH/CentOS 9, Ubuntu
22, etc.)
