Device hanging after raising .bss to/over 0x10000 (64kb)

I'm having a peculiar problem with my device in a memory heavy application, two of my libraries use statically allocated memory and one uses what i allocate with mem_manager. Overall memory usage doesn't seem to go past about 80kb per linker, but if i try to add mem manager blocks or FreeRTOS heap the result is same. My application won't run. Well to be honest i'm not sure my application doesn't run, but when take SEGGER debugger to it and halt it, it shows no exception. All it seems to me is that the device hangs.

Well then. I have found the problem and it sure was not where i expected it to be. The debugger I use (SEGGER J-Link) seems to have some difficulty connecting or finding the RTT control block when I raise the .bss high enough. I am able to circumvent this by resetting (and halting) the core before trying to read RTT output from it. It's an extra step, but it works.
