Bug #: 14387
Summary: Memory leak in gdb/python/py-stopevent.c:66
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: python
AssignedTo: unassigned@sourceware.org
ReportedBy: m@bruenink.de
Classification: Unclassified
In py-stopevent.c:66 a PyList is created which is than attached to a stop event
by calling create_breakpoint_event_object. This list is never garbage
collected.
Decrementing the reference count to the list after line 83 fixed the problem
for me.

Not only that, but pretty much every call to PyObject_SetAttrString
in gdb seems to be wrong.
