With 6.8, I think there is no way.

A long time ago there was a patch to add exception handling to the gdb
command language.  This is still in bugzilla somewhere.  I don't know
why it was never applied.

With a Python-enabled gdb you can write a command like the appended.
Then you can "ignore-errors do something".
