I can reproduce the hangs with native-gdbserver on s390x; at least for: display.exp step-over-trips-on-watchpoint.exp watchpoint-fork.exp watchpoints.exp A bisect shows the culprit: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=c65d6b55 Before this commit I see many FAILs with these tests, but no hangs. (The FAILs are due to lack of hardware watchpoint support for gdbserver on s390. At some time I had started a patch for that; maybe I should revive it...) Even knowing the first broken commit, I'm not sure yet what causes the hangs. I'll look more into that tomorrow. -- Andreas
