OverflowError: in method 'SBProcess_ReadPointerFromMemory', argument 2 of type 'lldb::addr_t'

Sharing the findings on lldb-dev.

Greg helped me figure out the issue, I need to check if symbol address is lldb.LLDB_INVALID_ADDRESS.

Things work fine now after the added checking.

The remaining issue is to figure out whether symbol.addr.file_addr or symbol.addr.load_addr should be used to get symbol address.

My test shows symbol.addr.file_addr should be used, at least for types defined in exetuables, contrary to what’s documented.
