Gdb + deprecated Python + gdb._execute_unwinders function is missing

[julien2412]

Hello,

Since yesterday and I don't know why, when launching make debugrun, I got:
mkdir -p /home/julien/lo/libreoffice/instdir
/home/julien/lo/libreoffice/solenv/bin/install-gdb-printers -a
/home/julien/lo/libreoffice/instdir -c
make -j 12  -rs -f /home/julien/lo/libreoffice/Makefile.gbuild   debugrun
Python Exception <class 'DeprecationWarning'> the imp module is deprecated
in favour of importlib; see the module's documentation for alternative uses: 
gdb: warning: 
Could not load the Python gdb module from `/usr/share/gdb/python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.

Once I get gdb command and type run --calc, I got, lots of this kind:
Starting program: /home/julien/lo/libreoffice/instdir/program/soffice.bin
--calc
Traceback (most recent call last):
  File "/home/julien/lo/libreoffice/instdir/program/libuno_sal.so.3-gdb.py",

    import gdb

    from imp import reload
  File "/usr/lib/python3.8/imp.py", line 31, in <module>
    warnings.warn("the imp module is deprecated in favour of importlib; "

    warnings.warn("the imp module is deprecated in favour of importlib; "

and at the end:
Python Exception <class 'NameError'> Installation error:
gdb._execute_unwinders function is missing: 
Python Exception <class 'NameError'> Installation error:

I'm on Debian testing updated every day.
I installed python3-gdbm and python3-gdbm-dbg

I runned "./autogen.sh && make clean && make" just to be sure there wasn't
any wrong remnants.

Any idea?

Julien
