Re: [lldb-dev] [cfe-dev] [8.0.0 Release] rc2 has been tagged

[Diana Picus via lldb-dev]

Uploaded ARM & AArch64:
9432315fe814e5edc667467bc1b3ce4817084edc
clang+llvm-8.0.0-rc2-aarch64-linux-gnu.tar.xz
fb7f587de673837c82da47209ec9d9ed72f9b27f
clang+llvm-8.0.0-rc2-armv7a-linux-gnueabihf.tar.xz

Same as before, ARM looks fine but we have a MSan failure on AArch64
(I haven't yet managed to reproduce it outside Jenkins though, I'll
try harder).

Cheers,
Diana

Re: [lldb-dev] [Release-testers] [8.0.0 Release] rc2 has been tagged

[Brian Cain via lldb-dev]

Any tips or suggestions on how to isolate or identify this defect?  It
seems non-trivial to bisect this failure.

Hans: presumably this bug should block the 8.0 release?
