Bug ID: 117372
Summary: std::list pretty printer: AttributeError: 'NoneType'
object has no attribute 'pointer'
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: simon.marchi at polymtl dot ca
Target Milestone: ---
I got this while debugging gdb with gdb. I have not been able to make a small
reproducer yet.
Steps:
1. Checkout binutils-gdb at commit 35d53ce6429a
2. configure with: ./configure 'CFLAGS=-g3 -O0' 'CXXFLAGS=-g3 -O0'
3. make
4. start gdb: ./gdb
5. attach using system gdb, or some other gdb configured to find the libstdc++
pretty printers
6. print current_program_space.objfiles_list
What I get is
(top-gdb) p current_program_space.objfiles_list
$1 = empty std::__cxx11::listTraceback (most recent call last):
File "/usr/share/gcc-14.2.1/python/libstdcxx/v6/printers.py", line 422, in
children
nodetype = lookup_node_type('_List_node', self._val.type).pointer()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'pointer'
It's the result of `lookup_node_type` that is None.
The system gcc version is "gcc (GCC) 14.2.1 20240910" (Arch Linux package)
The system gdb version used to attach is 15.2 (Arch Linux package)
