That looks to me like GDB crashed.  Check your ulimit, check for
core dumps in the testsuite directory.

I confirm it is not GDB crash.

Increase verbosity of dejagnu:
make RUNTESTFLAGS="gdb.base/long_long.exp -v -v" check

and check your log file in gdb/testsuite/gdb.log.  Maybe you try
to do the failing operation per hand and see if GDB crashes.
