1 week ago Commenting out some of the code gives a slightly different backtrace:

Description
Compiler crashes here: https://github.com/apple/swift/blob/70c54bb73980c94b975c7d9d8d6e2b0d78d731b6/lib/AST/ASTMangler.cpp#L1558C1-L1559C1
(WAS: I can attach the file that produces the crash, have been trying to reduce it but not succeeded so far. NOW, see reproducer below)
Reproduction
Stack dump
Expected behavior
No crash would be expected
Environment
This crashed with the latest 6.0 downloaded: https://download.swift.org/swift-6.0-branch/xcode/swift-6.0-DEVELOPMENT-SNAPSHOT-2024-06-19-a/swift-6.0-DEVELOPMENT-SNAPSHOT-2024-06-19-a-osx.pkg
But we originally have the crash in a production released version:
