#0 0x000000000003b100 in ?? ()
warning: GDB can't find the start of the function at 0x3b100.
GDB is unable to find the start of the function at 0x3b100
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 0x3b100 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.
#1 0x000000000003b100 in ?? ()
warning: GDB can't find the start of the function at 0x3b100.
Previous frame identical to this frame (corrupt stack?)
