[Bug python/12267] New: gdb.Value of type pointer has a negative address sometimes

http://sourceware.org/bugzilla/show_bug.cgi?id=12267

Summary: gdb.Value of type pointer has a negative address
sometimes
Product: gdb
Version: 7.2
Status: NEW
Severity: normal
Priority: P2
Component: python
AssignedTo: ***@sourceware.org
ReportedBy: ***@gmail.com


This problem was encountered when calling a function (using
gdb.parse_and_eval()) in a Python inferior that returns a PyObject *. This is
the result of a debug session with Pdb (the Python Debugger) inside gdb:

(Pdb) print gdbval
<unknown at remote 0x-80f8220>
(Pdb) print gdbval.address
None
(Pdb) long(gdbval)
-135234080L
(Pdb) print gdbval.type
PyObject *

As you can see, the address is negative when you print the value or try to
convert it to a Python long.

I tried to reproduce this but couldn't. Not too much info to work with here.
Do you have a more specific reproducer?

Probably a dup.
