core dump: O_CREAT without mode

[vigith]

I am getting a core dump when I am trying to start stored. This same error came when i tried to do make check. Could you please help me understand why this error is coming?

Also, could you please be kind enough to tell me how to make this program run on a 3 node cluster. I am not sure how to fill in the config file (currently my config file is empty). I get the same error with or without a config file.

In https://github.com/jbeverly/rangexx/blob/master/librange/util/fdraii.h#L61 I made the following change and it seems to have resolved the issue. I am not sure whether it is the right patch though.

-            fd_ = open(filename.c_str(), mode);
+            fd_ = open(filename.c_str(), mode, 0644);
