backtrace in core on arm-linux

[Baurzhan Ismagulov]

Hello all,

I can't get the backtrace in a core file on arm-linux. To reproduce:

int main(void) {
	for (;;) printf("Hello, world!\n");
}

Compile, run under gdb HEAD, press Ctrl-\, bt works:

#0  0x400cb530 in write () from /lib/libc.so.6
#1  0x40080c40 in _IO_new_file_write () from /lib/libc.so.6
#2  0x4007f764 in new_do_write () from /lib/libc.so.6
#3  0x4007f86c in _IO_new_do_write () from /lib/libc.so.6
#4  0x400800f0 in _IO_new_file_overflow () from /lib/libc.so.6
#5  0x400816c4 in __overflow () from /lib/libc.so.6
#6  0x40078048 in puts () from /lib/libc.so.6
#7  0x000084bc in main () at b.c:7

Run from shell, press Ctrl-\, open core, bt shows:

#0  0x400cb530 in write () from /lib/libc.so.6
#1  0x00003704 in ?? ()
#2  0x00003704 in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)

How can I fix this?

Thanks in advance,
