[lldb-dev] OverflowError: in method 'SBProcess_ReadPointerFromMemory', argument 2 of type 'lldb::addr_t'

[Lei Kong via lldb-dev]

I ran into the error in the subject when running a python script with "script myfile.myscript()".
 
The value addr_t parameter used is 0x0000000001223f68, the following works fine:

(lldb) scr
Python Interactive Interpreter. To exit, type 'quit()', 'exit()' or Ctrl-D.
>>> e = lldb.SBError()
>>> ptr = lldb.process.ReadPointerFromMemory(0x0000000001223f68, e)
>>> print ptr
0
>>> 
 
Any suggestion how to further investigate? Thanks.
 
myfile.myscript() calls the following function in a loop (iterate through all vtable symbols), which contains the call ReadPointerFromMemory.
 
def dump_vtbl(vtableAddr) :
    error = lldb.SBError()
    vtableEndAddr = lldb.process.ReadPointerFromMemory(vtableAddr+8, error)
    if not error.success :
        return False
    print "vtable: [%0.16x, %0.16x)" % (vtableAddr, vtableEndAddr)
    for addr in range(vtableAddr, vtableEndAddr, 8) :
        print "read from address %.016x" % addr
        try:
            funcAddr = lldb.process.ReadPointerFromMemory(addr, error)
        except:
            sys.exc_clear()
            continue
        if not error.success :
            continue
