Probably all of these, for starters:

Don't crash when hostname is empty. StringRef will assert and kill your
program.

Don't crash when trying to capture persistent variables in a block.
Reports an error instead. We can fix this later to make persistent
variables
work, but right now we hit an LLVM assertion if we get this wrong.

Don't crash if we have a DIE that has a DW_AT_ranges attribute and yet
the SymbolFileDWARF doesn't have a DebugRanges. If this happens print a
nice error message to prompt the user to file a bug and attach the
offending DWARF file so we can get the correct compiler fixed.
