How to disable the stack trace in c++ glog?

I applied Glog to output some runtime information in my code, and I want to disable the stack trace function to protect the detail of the code. But I find the Glog is default to track the stack trace and log it to std err or log file, and there is no FLAGS_xx to disable it.

And I tried to #undef some of the stack trace related macro such as HAVE_STACKTRACE, but it doesn't work.

Do you have any elegant method to do this?
