On Linux, given a core dump file, an executable and its symbols, is it possible
to do the following in LLDB (maybe with a LLDB extension)?
1. Get the list of all C++ virtual types (classes with virtual function table)
2. Search the whole address space to find all instances of such objects? (false

Should I use lldb::SBTarget::GetModuleAtIndex() to get all modules and then
lldb::SBModule::GetSymbolAtIndex() to go through all symbols?
Thanks.

I wrote a lldb type summary provider for wstring with 16bit wchar on Ubuntu
16.04.Things work fine if I manually do the following in lldb:(lldb) script
import mytypes
(lldb) type summary add -F mytypes.wstring_SummaryProvider "std::__1::wstring"
I tried to make things easier with auto-loading by

I ran into the error in the subject when running a python script with "script
myfile.myscript()".
The value addr_t parameter used is 0x01223f68, the following works fine:

rinting the type of the value you are passing in the line:
vtableEndAddr = lldb.process.ReadPointerFromMemory(vtableAddr-8, error)
print type(vtableAddr)
print type(vtableAddr-8)
It seems like it thinks vtableAddr doesn't fit into a lldb::addr_t which is a
uint64_t
