Bug ID: 49452
   Summary: Assertion failed in TypeSystemSwiftTypeRef.cpp when
running 'thread list' crashing lldb on Linux
   Product: lldb
   Version: 10.0
  Hardware: PC
OS: Linux
Status: NEW
  Severity: normal
  Priority: P
 Component: All Bugs
  Assignee: lldb-dev@lists.llvm.org
  Reporter: j...@mac.com

I tried to reproduce this but was unable manually, but ": lldb -replay
/tmp/reproducer-e6ba30" did reproduce it and it crashed again.

I've put up the reproducer as a tar.gz at:
https://www.icloud.com/iclouddrive/0g3sE3slMVet4lypF7-xHbuGg#reproducer-e6ba30

it is 37.5MB and can't be attached.

This is with:
(lldb) version
lldb version 10.0.0
Swift version 5.4-dev (LLVM d28e4b973b2abd9, Swift d378e707988c0ef)

Trying to run 'thread list' gave me the following broken assertion:
-
(lldb) frame info
frame #0: 0x556a505e NIOPerformanceTester`UInt32.init(value=(b12 = 0,
b3 = 0)) at IntegerTypes.swift:52:38
(lldb) fr v
(NIO._UInt24) value = (b12 = 0, b3 = 0)
(UInt32) self = 0
(UInt32) newValue = 0
(lldb) fr v -a 
(UInt32) self = 0
(UInt32) newValue = 0
(lldb) thread list 
1 != 0

This is a Swift issue which isn't part of LLVM. You probably want to file this
at https://bugs.swift.org/ (You can just copy-paste the same bugreport which
seems to have all the relevant information. Thanks!)

[lldb-dev] IMPORTANT NOTICE - Subscription to Mailman lists disabled immediately

2021-03-05 Thread Tanya Lattner via lldb-dev 
All,

We need to immediately disable subscription capabilities to all LLVM Mailman 
lists.

The current Mailman server is being abused by subscribing valid email addresses 
to our lists and because the list requires confirmation, the email address gets 
“spam”. An email address is subscribed upwards of 100 times in a short period 
of time in many cases. AWS has threatened to turn off our instance unless we 
take immediate action. Given the time frame of the situation (24 hours to 
resolve), we have no choice but to disable all new subscription capabilities as 
we can not distinguish between a real subscription attempt versus the abuse. 

Those currently subscribed should see no changes or impact to their workflow. 

I am sure this raises a lot of questions for the LLVM community and we are 
working hard and as quickly as possible on a permanent solution to this 
situation.

Thanks,
Tanya Lattner
LLVM Foundation
