# This test covers a case where SIGSTOP has been configured to be
|
|
# passed to the target with GDB's 'handle' command, and then a
|
|
# multi-threaded inferior encounters an event that causes all threads
|
|
# to be stopped.
|
|
#
|
|
# The problem that (used) to exist was that GDB would see the SIGSTOP,
|
|
# but decide to ignore the signal based on the handle table.
