# Test that "start"ing an inferior does not inadvertently stop in another
# inferior.
#
# To achieve this, we start inferior 1 in background, which sleeps for a bit
# before reaching its main function. We then "start" inferior 2, which also
# sleeps before reaching its main function. The goal is that inferior 1
# "crosses" inferior 2's start breakpoint (at the time of writing this test, the
# breakpoint inserted for start is global and has locations in both inferiors).
# A buggy GDB would report a breakpoint hit in inferior 1.
