It is dependent (like the rest of gdb.gdb/) on the compiler used to
build gdb and the optimization level.  Do you use 2.95.3 +
optimization to build any of your GDB's?

Oh, very neat.  I don't know why I didn't ever see this one; I was
referring to one of the new MI tests.

I get a lot of garbage core.NUMBER files but they're from one of the
other tests... a threaded one I think.

I've never seen the ERRORs; how bizarre... I'll look at your logs
