Crash/Stackoverflow when using gDebug() before initializing bsf
I tried to put some log output before I actually open the window and noticed some very strange behavior: The bs::LogEntry-class tries to access bs::Time, which then goes on to report a crash because it's not initialized.
The crash-reporter then goes and tries to write a log-entry, which of course fails and causes another crash, and so on. For some reason, I don't get a stack overflow error, the program just hangs and does nothing.
I understand that maybe one isn't supposed to use gDebug() before the application is initialized (which also opens the window), but I feel like this is a case which could be checked before sending the program into crashing over and over again.
Here is some of the initial call stack:

Thanks, I experienced this one before. It's not high priority but I agree it should eventually be resolved.
