This is a very old and longstanding bug https://bugs.llvm.org/show_bug.cgi?id=40669
I recently encountered it running Delve (the Go Debugger) on OSX.
Per these stack overflow comments https://stackoverflow.com/questions/26829119/how-to-make-lldb-ignore-exc-bad-access-exception/32724035#comment94068788_26853954 the fix appears trivial.
Does the fix proposed fix there make sense? To simply allow the LLDB to catch the signal?
I tried to make the change myself but ran into other issues building lldb.
