When gdb loads an elf file of a newer or older version of the firmware
being debugged, or when the firmware is not running yet, there's a high
probability of FreeRTOS variables to be read incorrectly, thus leading to
an attempt to allocate an enourmous amount of memory. Without this check
OpenOCD simply crashes and that's mad confusing.
