[SR-11282] LLDB REPL code completion assertion failure #4482
Comments
Fixed in master, but did not make 5.1. :-( cc @dcci |
Looking. |
Ugh, I can't reproduce on 5.1 at all :| swift % ./build/Ninja-DebugAssert+stdlib-Debug/lldb-macosx-x86_64/bin/lldb --repl
Welcome to Swift version 5.1-dev (LLVM 688b71e2f9, Swift 20b8d4c30b).
Type :help for assistance.
1> func foo(_ x: String) { print(x) }
2> foo("hello"
Available completions:
!= String -> Bool
+ String -> String
... -> PartialRangeFrom<String>
... String -> ClosedRange<String>
..< String -> Range<String>
< String -> Bool
<= String -> Bool
== String -> Bool In fact, the code that causes the crash which I fixed doesn't really exist on 5.1 |
Do you happen to know which commit(s) fixed this? We have a branch with this problem and we might want to cherry-pick the fix onto it if possible. |
Sure, let me find them. |
These two, I think: Please let me know if you still have issues and I'll try looking at them. |
Comment by Yaroslav (JIRA) I'm still facing this issue. Issue appears on macOS 10.15.2, not on Linux. The issue appears when I'm trying to import any module, like: $ swift
