  16 # Regression test for PR15693.  A breakpoint with a condition that
  17 # calls a function that evaluates false would result in a spurious
  18 # *running event sent to the frontend each time the breakpoint is hit
  19 # (and the target re-resumed).  Like:
  20 #
  21 #  -exec-continue
  22 #  ^running
  23 #  *running,thread-id="all"
  24 #  (gdb)
  25 #  *running,thread-id="all"
  26 #  *running,thread-id="all"
  27 #  *running,thread-id="all"
  28 #  *running,thread-id="all"
