Problem reading corefiles on ARM

Hello,

I'm trying to test the GDB ability to analyze ARM coredumps:

-bash-3.2# gdb t core.967

4 abort();
5 return a+b;
6 }
7 main()
8 {
9 printf("hello\n");
10 foo(10, 20);
(gdb)
11 }
(gdb)

My environment: ARM native GDB-6.7, toolchain is gcc-4.2.2,
binutils-2.17.50.0.12, glibc-2.6, built as cross-tools,
arm-linux-eabi. Target running kernel 2.6.22.6.

Is this ARM GDB bug? I tried GDB 6.3 with non-eabi ARM toolchain
(gcc-4.0.0) running the same kernel - all the same.

Thanks for any help.

Regards,
Sergei
