Differences From Artifact [a50325ba8b]:

• File src/exceptions/OFException.h — part of check-in [a889f21180] at 2013-05-22 20:36:31 on branch trunk — Don't depened on execinfo.h for backtraces.

  Instead, __builtin_return_address() is used now. This makes backtraces
  available on many platforms, it even works if dladdr is missing (it does
  not show symbol names then, though). (user: js, size: 1897) [annotate] [blame] [check-ins using]

To Artifact [3edc7f9b6e]:

• File src/exceptions/OFException.h — part of check-in [f2a8bdf254] at 2013-05-25 11:40:28 on branch trunk — Switch back to backtrace().

  The reason is that __builtin_frame_address(n) for n > 0 seems to just
  crash on most platforms when -fomit-stack-pointer is specified, which
  seems to be the default for many platforms on -O2. The documentation
  says that __builtin_frame_address() should return NULL in case it can't
  get the frame, but it seems to crash instead.

  Therefore, this commit reverts to using backtrace() from execinfo.h, if
  available. However, as __builtin_frame_address() seems to always work on
  PPC (even with -fomit-frame-pointer) and seems to be the only way to get
  a backtrace on the Wii, this is still used if backtrace() is unavailable
  and __ppc__ defined. (user: js, size: 1912) [annotate] [blame] [check-ins using]
