Hey Patrick,
Looking at the BuildBot logs today, I found that this new test is
failing occasionally on native-extended-gdbserver testing. Take a look
at the following build:
<http://gdb-build.sergiodj.net/builders/Debian-x86_64-native-extended-gdbserver-m64/builds/1429>
You can see that gdb.base/gdbinit-history.exp failed:
PASS -> FAIL: gdb.base/gdbinit-history.exp: truncation: appending: server show commands
PASS -> FAIL: gdb.base/gdbinit-history.exp: truncation: creating: server show commands
The gdb.log is here:
<http://gdb-build.sergiodj.net/cgit/Debian-x86_64-native-extended-gdbserver-m64/.git/plain/gdb.log?id=2abe37b834f73838c68e1f843bdd612cef4a2ae3>
I haven't really investigated to determine what's going on here, but let
me know if you need any help with this.
Thanks,
