Problem

Test test_numba_integration::test_array_adaptor causes segmentation fault (SIGSEGV) when using Numba JIT compilation on RHEL 9.6.

Root Cause

The test triggers a segfault in Numba LLVM backend, likely due to version incompatibility with RHEL 9.6 or memory access violation.

Impact

• Tests failing: 1
• Severity: Low - Numba is optional integration
• Production impact: None - Most users do not use Numba with PyTorch
• Error: IndexError followed by SIGSEGV

Proposed Solutions

Option 1: Exclude test if Numba not required
Option 2: Rebuild Numba specifically for RHEL 9.6
Option 3: Update to newer Numba version with RHEL support

Acceptance Criteria

• [ ] Root cause identified
• [ ] Fix implemented (rebuild, update, or exclusion)
• [ ] Test passes without segfault
• [ ] Or: Numba integration marked as unsupported on RHEL
