My main worry was what the consequences for a user of hitting this undefined 
behaviour are, since it's entirely possible a user will have such code. The UB 
reference was what worried me, since that could crash lldb or have similarly 
bad consequences.

I'm still unsure quite what could happen, but I'll believe everyone's 
reassurances that it's not a problem.
