[Bug backtrace/10310] New: (GNU/Linux:GCC:C lang: ARM platform) Core dump backtrace on stripped binaries Halts in 2 levels

Backtrace on stripped binaries in ARM platform do not go beyond two levels. gdb
throws 'identical frame' (corrupt stack) message. Noticed that gdb takes the
path of stack unwinding using frame pointer and standard stack frame structure.
How reliable is this?
Steps to reproduce:
1) Just build using the following compiler options
-mabi=aapcs-linux -mno-thumb-interwork -fno-strict-aliasing -fno-common -Os
-fno-strict-aliasing -fno-common -marm -mhard-float -mfloat-abi=softfp -mfpu=vfp
-mno-sched-prolog -march=armv5te -mtune=marvell-f -fno-optimize-sibling-calls
-fno-stack-protector -fno-omit-frame-pointer -fPIC.
2) send sigsegv or sigabrt to the app.
3) core dumped.
4) arm-none-linux-gnueabi-gdb app core
5) bt gives only two levels of addresses and halts with the message
previous frame identical to this frame (corrupt stack?).

Noticed similar output in my x86 setup also.. except that it prints the same
couple of addresses twice before exiting with the 'identical frame' message.
