[lldb-dev] LLDB crashes on "frame variable"

[Enrico Granata]

This looks like an issue with your “custom” (i.e. non OS-provided) version of Python
Does this work if you redirect to the system-wide Python.framework?
Most probably some of your variables require a Python data formatter, and this is causing the script interpreter to start, and that in turn causes this issue
A workaround is to type

(lldb) type category disable *

but this will disable all data formatters, and might not be what you want given that you are extensively using the STL

My first bet would be to try the same thing with the Python built into OSX and then take it from there
