[PR] [DNM][CI] Debug spark-test-spark41 SIGSEGV in NativeBackendInitializer [gluten]
jackylee-ch opened a new pull request, #12552:
URL: https://github.com/apache/gluten/pull/12552
## What changes were proposed in this pull request?
**DNM — Debug-only PR for issue #12534.**
`spark-test-spark41` / `spark-test-spark41-slow` fail consistently on every recent Velox Backend (x86) run. The forked surefire JVM dies with SIGSEGV (exit 134) while running `ColumnarBatchTest` (the first `VeloxBackendTestBase`-based suite), inside native backend initialization:
```
siginfo: si_signo: 11 (SIGSEGV), si_code: 1 (SEGV_MAPERR), si_addr: 0x0000000000000030
C [libgluten.so+0xdb73a4]
j org.apache.gluten.init.NativeBackendInitializer.initialize(...)
j org.apache.gluten.backendsapi.velox.VeloxListenerApi.initialize(...)
j org.apache.gluten.test.VeloxBackendTestBase.setup()
```
(hs_err captured via the diagnostics steps borrowed from #12551's run.)
This PR trims `velox_backend_x86.yml` to only `build-native-lib-centos-7` + the two spark41 jobs, and adds crash-diagnostics steps (print/upload `hs_err_pid*.log`, surefire `*.dumpstream`, cores) so we can iterate quickly and bisect the cause.
## How was this patch tested?
CI only.
