at91sam7 GDB : strange warning

[Roman Mashak]

I'm working on a firmware built for AT91SAM7 linked to run from SRAM.
When loading the image in GDB, I get this warning:

_startup () at Cstartup.S:62
62                      B           InitReset           /* 0x00 Reset handler */
Current language:  auto; currently asm
Expected an decimal digit (0-9)
...
<followed by the sane messages from .gdbinit commands>

Application is being debugged and run perfectly, without significant
issues. I only wonder the root of that warning. I googled for it, but
with no luck. Hope someone here will give a hint.

Thanks.
