Backtrace stopped: previous frame identical to this frame (corrupt stack?)

I am using arm cortex M3 (LPC1833 controller), I created manually stack overflow in code and trying to debug through GDB I am facing below issue of the corrupted stack in GDB tool on windows platform. My output of GDB is as shown below in that instead of the function name its showing "?? ()". Could anyone help to figure out why it's not showing function name?

My output:-

C:\HardFault_LLC>arm-none-eabi-gdb OpImage_BC.axf -ex "set target-charset ASCII" -ex "target remote | CrashDebug --elf OpImage_BC.axf --dump MainCrashDump.txt"
