Bug Report Possible Memory Leak

Update: found more data, and posted an official bug.

I am rather new to OBS, so I apologize if this is a known issue and I just didn't find it while looking around the forum.

I have compiled the latest code base (from master branch) because of a bug in 0.14.2.

When I run OBS it seems to be fine, and doesn't start gobbling up memory. Then about a minute into a stream/recording it starts going nuts and eating memory. At first I thought it was triggered by adding too many screens, or cameras. I just ran a test where I added 1 screen, and then 1 camera, and it happened.

I have attached the log (which to the untrained eye [mine] looks clean), and the profiler_data.

Fedora 23 (all updates)
Gnome 3.18.5

CPU: Intel(R) Core(TM) i5-4200M CPU @ 2.50GHz
Memory: 16GB (10GB free at start of recording)

Happy to provide any more information you need.

Unsure how it is related, but when I run obs this process goes nuts in CPU and Memory (I suspect it is related to the problem).

/usr/libexec/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -nolisten tcp -background none -noreset -keeptty -verbose 3

This is running before and after I stop OBS, but when OBS is running, this goes nuts.
