Github Issue: Swift 5.9.2 Crash while running GlobalPropertyOpt SIL Optimization · Issue #71274 · apple/swift · GitHub
We're getting a compiler crash while running release builds (build with optimization).
Wasn't able to reproduce the issue because the module that's being built contains hundreds of swift files.
Stack trace
1. Apple Swift version 5.9.2 (swiftlang-5.9.2.2.56 clang-1500.1.0.2.5)
2. Compiling with the current language version
---
4. While evaluating request ExecuteSILPipelineRequest(Run pipelines { PrepareOptimizationPasses, EarlyModulePasses, HighLevel,Function+EarlyLoopOpt, HighLevel,Module+StackPromote, MidLevel,Function, ClosureSpecialize, LowLevel,Function, LateLoopOpt, SIL Debug Info Generator } on SIL for FaireCore)
5. While running pass #1016146 SILModuleTransform "GlobalPropertyOpt".

zsh: segmentation fault LLVM_SYMBOLIZER_PATH= -c -filelist -supplementary-output-file-map
Setting the path for LLVM_SYMBOLIZER_PATH doesn't have any effect.
Need some help to colect further information to debug this issue and find the root cause.
I'm trying to run the optimization phase manually but I'm not having success building swift/lib/SILOptimizer/IPO that contains the GlobalPropertyOpt optimization pass.
