More proof:
I rebuilt GDB 10.1 with this patch applied:
--- a/gdb/python/py-inferior.c
+++ b/gdb/python/py-inferior.c
@@ -394,7 +394,7 @@ infpy_threads (PyObject *self, PyObject *args)
try
{
- update_thread_list ();
+ // update_thread_list ();
}
catch (const gdb_exception &except)
{
Just to see, and this version of GDB works fine.
There's something unpleasant about invoking update_thread_list() while
we are attempting to pretty-print stack variables; it must mess with
some global state somewhere that doesn't expect to be messed with, at
that time.
