If gdb attaches to a process that either has no controlling terminal, or the controlling terminal differs from the one gdb is running under, break/^C doesn't interrupt the debugged process on Solaris. Fixed as follows, analogous to what all all other targets do. Patch from the PR, recently re-submitted by Brian Vandenberg. Tested on amd64-pc-solaris2.11, sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu. 2019-02-28 Brian Vandenberg <phantall@gmail.com> Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> gdb: PR gdb/8527 * procfs.c (proc_wait_for_stop): Wrap write of PCWSTOP in set_sigint_trap, clear_sigint_trap. gdb/testsuite: PR gdb/8527 * gdb.base/interrupt-daemon-attach.c, gdb.base/interrupt-daemon-attach.exp: New test.
