unhandled exception in cpychecker

[davidmalcolm]

This unhandled exception comes from gdb's varobj.c. I haven't tried reducing it.

{{{ ../../archer/gdb/varobj.c: In function ‘varobj_invalidate_iter’: ../../archer/gdb/varobj.c:4226:22: error: Unhandled Python exception raised calling 'execute' method Traceback (most recent call last): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/init.py", line 79, in execute self._check_refcounts(fun) File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/init.py", line 85, in _check_refcounts dump_json=self.dump_json) File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/refcounts.py", line 4361, in check_refcounts maxtrans) File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/refcounts.py", line 4216, in impl_check_refcounts limits=limits) File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3073, in iter_traces depth + 1): File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 3045, in iter_traces trace_with_err.log(log, 'FINISHED TRACE WITH ERROR: %s' % err) File "/home/tromey/Space/Trunk/gcc-python-plugin/libcpychecker/absinterp.py", line 1056, in str % (self.expr, self.state.loc.get_stmt().loc)) AttributeError: 'NoneType' object has no attribute 'loc' }}}

The line in the error: {{{ var->root->is_valid = 0; }}}

This particular function doesn't use any Python API at all.
