compile and run issue about dbx1000

[yxymit]

Did you change the configuration file? If so, can you send me the config file you used?

Thanks

[egg-west]

I think I did not change the configuration.

[yxymit]

Did you 1) checkout the repo, 2) run 'make', and 3) run './rundb'? Also, can you try running the program with a debugger (e.g., gdb) and let me know which line causes the trouble? Right now I don't have enough information to understand what the issue is.

[egg-west]

I did nothing except editing the test.py to make it work in python 3.6. Then I run the './rundb', the results is like
mem_allocator initialized!
Segmentation fault (core dumped)

And I will try to find out which line caused this.
Thank you.

I got the results below in gdb:

I guess the problem is caused after and close to main.cpp:44

Do you have GRAPHITE_HOME defined in your system? If so, this is a very rare bug triggered by some legacy code. I have just pushed some changes to the repo. Specifically,

        init_schema( path );

Let me know if this works.

[egg-west]

It works now.
I am not sure about GRAPHITE_HOME.

Thank you sincerely.
