linux_nat_is_async_p currently always returns true, even when the target is _not_ async. That confuses gdb_readline_wrapper/gdb_readline_wrapper_cleanup, which force-disables target-async while the secondary prompt is active. As a result, when gdb_readline_wrapper returns, the target is left async, even through it was sync to begin with. That can result in weird bugs, like the one the test added by this commit exposes. Ref: https://sourceware.org/ml/gdb-patches/2015-01/msg00592.html gdb/ChangeLog: 2015-01-23 Pedro Alves <palves@redhat.com> * linux-nat.c (linux_is_async_p): New macro. (linux_nat_is_async_p): (linux_nat_terminal_inferior): Check whether the target can async instead of whether it is already async. (linux_nat_terminal_ours): Don't check whether the target is async. (linux_async_pipe): Use linux_is_async_p. gdb/testsuite/ChangeLog: 2015-01-23 Pedro Alves <palves@redhat.com> * gdb.threads/continue-pending-after-query.c: New file. * gdb.threads/continue-pending-after-query.exp: New file.
