The 'next' command does not work for this simple program on mips/mipsel.
#include <stdio.h>
int main(int argc, char **argv)
{
printf("Hello world.\n");
return 0;
}

warning: Warning: GDB can't find the start of the function at 0x400a40.
GDB is unable to find the start of the function at 0x400a40
and thus can't determine the size of that function's stack frame.
This means that GDB may be unable to access that stack frame, or
the frames below it.
This problem is most likely caused by an invalid program counter or
stack pointer.
However, if you think GDB should simply search farther back
from 0x400a40 for code which looks like the beginning of a
function, you can increase the range of the search using the `set
heuristic-fence-post' command.
