[llvm-dev] Pass segmentation fault after llvm_shutdown.

[Friedman, Eli via llvm-dev]

I ran into a similar problem a while ago; see 
https://reviews.llvm.org/D30107 and https://reviews.llvm.org/D33515 .  
You get the unusual stack trace because it's trying to call a destructor 
in shared library which was already unloaded.

I thought we had fixed that, but maybe not?  Looking again, it looks 
like the patch got reverted and I didn't notice.
