What is the backtrace (use "bt" command in gdb after crash)?

I just built the master branch and got the same problem.

Here is the gdb output:

Thanks, is there a command I need to change in order to pull master?

Yes, this is likely the same issue as: https://github.com/BitShares/bitshares/issues/959

It will be officially fixed in 0.4.25 but is already included in the current master branch so you can pull master if desired.

Try pulling the latest, rather than the tagged 0.4.24 version.  There was a crash patched that isn't in a tagged release yet.

output when I run under gdb

Hi I recently began having difficulty running the client. When I attempt to start, I get

Loading blockchain from: /home/ubuntu/.BitShares/chain
Loading config from file: /home/ubuntu/.BitShares/config.json
Not starting RPC server, use --server to enable the RPC interface
Segmentation fault (core dumped)

It was compiled in ubuntu 14.04 if that makes any difference

thanks
