// Produce stack trace.
//
// There are three different ways we can try to get the stack trace:
//
// 1) 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.
//
// 2) The libunwind library. This is still in development, and as a
// separate library adds a new dependency, abut doesn't need a frame
// pointer. It also doesn't call malloc.
//
// 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().
//
// 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.

# if defined(HAVE_EXECINFO_H)
