hi all,

i was going to bring this up at the meeting today, but there was no time. swift-symbolgraph-extract is still broken (as of DEVELOPMENT-SNAPSHOT-2022-11-01-a) when trying to emit the standard library Swift module:

swift-symbolgraph-extract crashes when trying to emit the 'Swift' module

bug SymbolGraphGen

we used to be able to generate the symbolgraph for the standard library with: … ``` swift symbolgraph-extract \ -target x86_64-unknown-linux-gnu \ -output-dir . \ -module-name Swift ``` which worked fine all through the winter, spring, and summer. but now it just crashes the toolchain: ``` $ swift symbolgraph-extract -target x86_64-unknown-linux-gnu -output-dir . -module-name Swift swift-symbolgraph-extract: /home/build-user/llvm-project/llvm/include/llvm/ADT/SmallVector.h:291: llvm::SmallVectorTemplateCommon::reference llvm::SmallVectorTemplateCommon<const swift::ProtocolCompositionType *, void>::back() [T = const swift::ProtocolCompositionType *]: Assertion `!empty()' failed. PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace. Stack dump: 0. Program arguments: /home/ec2-user/.swiftenv/versions/DEVELOPMENT-SNAPSHOT-2022-10-03-a/usr/bin/swift-symbolgraph-extract -target x86_64-unknown-linux-gnu -output-dir . -module-name Swift 1. Swift version 5.8-dev (LLVM c3aebe50177cd03, Swift 3f020375e568042) ```

needless to say, the standard library is a very important symbolgraph, and we have been unable to build it since DEVELOPMENT-SNAPSHOT-2022-09-22-a. so any updates on the status of this issue would be greatly appreciated
