This is regrettably large, but easy to repro: - Unzip the file - `llc gpu_object_lifetime.runtime.ll` - See the assertion failure and stack dump (pasted below): Assertion failed: (!(Elmt.getFragmentOrDefault() == Next.getFragmentOrDefault())), function operator(), file AssignmentTrackingAnalysis.cpp, line 2020. PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace. Stack dump: 0. Program arguments: /Users/srj/llvm-17-install/bin/llc gpu_object_lifetime.runtime.ll 1. Running pass 'Function Pass Manager' on module 'gpu_object_lifetime.runtime.ll'. 2.
