Several failures like this one seem to indicate that a broken gdb is installed on the linux-mips64-rtrk builder. It should either be upgraded to a fixed version, or removed (or removed from $PATH) so that the tests will skip.

--- FAIL: TestGdbPanic (3.84s)

Same for TestGdbBacktrace, TestGdbConst, TestGdbAutotmpTypes, TestGdbPython.

The builder has 32-bit user space. I don't think 32-bit gdb can handle 64-bit programs.

I've built mips64 big-endian gdb and installed it onto builder and it seems that gdb tests are passing.

Thanks @milanknezevic !

I think we can close this. No more failure on dashboard now.
