[lldb-dev] [APT] lldb crashes on sturtup

[Eugene Kosov via lldb-dev]

Hello.

I have installed clang and  lldb from here
http://llvm.org/apt/
deb http://llvm.org/apt/vivid/ llvm-toolchain-vivid main
deb-src http://llvm.org/apt/vivid/ llvm-toolchain-vivid main

lldb crashed on startup every time.

Program received signal SIGSEGV, Segmentation fault.

Looks like a crash in static/global variable constructor.

I've tried to build lldb from sources using cmake and it works like a charm.

Any suggestions on how to fix that? My laptop is old and slow. That's why I prefer deb packages over building from sources.

Sorry in case if I wrote to a wrong place.
