I have installed GDB 7.2 32 bits and 32 bits buildslaves are green.
Nevertheless 64 bits buildslaves are failing test_gdb.

Is there any expectation that a 32 bits GDB be able to debug a 64 bits
python?. If not, gdb test should compare "platform.architecture()" (for
python and gdb in the system) and run only when they are the same. If
this should work, I would open a bug and maybe spend some time with it.

But before thinking about investing time, I would like to know if this
mix is actually expected or not to work.

If not, I would consider to install a 64 bits GDB too and do some tricks
(like using an "/usr/local/bin/gdb" script wrapper to choose 32/64
"real" gdb version) to actually execute "test_gdb" in both buildslaves
(they are running in the same physical machine).

Any advice?

PS: I am talking about AMD64 OpenIndiana buildbots. Haven't check others.
