[Bf-cycles] Crashing renders on custom builds

Hi Sergey,

I rebuilt with RelWithDebInfo target and ran a GDB backtrace after the 
crash. I'm including the corresponding generated crash log, which is 
still pretty similar to the old logs. Other than that backtrace, I'm not 
seeing any useful readout in console, either during GDB run or regular 
terminal run.
