Stack Trace

This is a Mac OS X / GDB counterpart to Stack Trace pattern previously described for Windows platforms (Volume 1, page 395). Here we first show a stack trace when symbols are not available and then show how to apply symbols:

(gdb) bt
#0 0×000000010d3b0e90 in ?? ()
#1 0×000000010d3b0ea9 in ?? ()
#2 0×000000010d3b0ec4 in ?? ()
#3 0×000000010d3b0e74 in ?? ()
