Yeah I used the bt command, which gave exactly the same output as the initial output. However you'll have to bear with me here, as I am new to gdb, so there is the possibility I'm just not doing things right at all.

I've just recompiled again after configuring with --enable-debug, and for completeness here's all the output from gdb:

GDB is unable to find the start of the function at 0x7572d0
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 0x7572d0 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.
