--- Comment #2 from Michael Pratt <mpratt at google dot com> ---
I'm still seeing the same behavior at 3eb651743e06fb360687a26be87bc6b710fc7=
066
("Implement missing powerpc mtspr and mfspr extended insns").

$ gdb/gdb -nx -batch -ex 'run' --args sleep 60 </dev/null 2>&1 | cat
Python Exception <type 'exceptions.ImportError'> No module named gdb:
gdb/gdb: warning:
Could not load the Python gdb module from `/usr/local/share/gdb/python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=3D/path/to/gdb/data-directory.=20
zsh: abort      gdb/gdb -nx -batch -ex 'run' --args sleep 60 < /dev/null 2>=
&1 |
zsh: done       cat=20=20=20

$ pkill -WINCH gdb

Same crash location:
