Package: gdb
Version: 7.6.2-1.1
Severity: important
Dear Maintainer,
A recent upload of gdb switched to python3 instead of python2.
Even if you really think a python3 gdb is useful, it should not be the
default, e.g. ship a gdb package using python2 and a gdb-python3 package
for people who don't like working software.
Besides the obvious breakage in every pretty-printer ever written (there
are more packages than libstdc++, you know!), it also breaks gdb in strange
ways. For example, after converting my pretty-printers to python3, I get
a python exception when just running 'info pretty-printer'.
(gdb should not be using copy.copy at all here)
(gdb) set python print-stack full
(gdb) info pretty-printer
