Comment(by promac@…):

 Replying to [comment:2 iggames@…]:
 > The upstream bug is stuck because no one can get the debug info he asked
 for. I took a stab at this myself, and found that I could not reproduce
 the crash if I disabled optimization (I was trying to include debug
 symbols with -g, and http://stackoverflow.com/questions/1370945/xcode-3-2
 -llvm-no-local-symbols-when-debugging suggested that optimization might
 get in the way of this):

 macports take some action here (such as removing the -O2 flag by default)?
 Or does the fact that -O2 causes the problem suggest a particular sort of
 fix in the product?

 I can confirm that suppressing -O2 fixes this issue.

 That is exactly the same problem I have when running CGAL applications on
 Lion.
 Random crashes if I use -O2.
