-// There are three different ways we can try to get the stack trace:
-//
-// 1) The libunwind library.  This is still in development, and as a
-//    separate library adds a new dependency, but doesn't need a frame
-//    pointer.  It also doesn't call malloc.
-//
-// 2) Our hand-coded stack-unwinder.  This depends on a certain stack
-//    layout, which is used by gcc (and those systems using a
-//    gcc-compatible ABI) on x86 systems, at least since gcc 2.95.
-//    It uses the frame pointer to do its work.
-//
-// 3) The gdb unwinder -- also the one used by the c++ exception code.
-//    It's obviously well-tested, but has a fatal flaw: it can call
-//    malloc() from the unwinder.  This is a problem because we're
-//    trying to use the unwinder to instrument malloc().
-//
-// 4) The Windows API CaptureStackTrace.
-//
-// Note: if you add a new implementation here, make sure it works
-// correctly when GetStackTrace() is called with max_depth == 0.
-// Some code may do that.
