Comment (by hinder):

 I agree that we should be careful, and in my judgement the effect of
 adding some additional debugging symbols should be minor, in comparison to
 other changes that you can imagine.  Of course we cannot ever be sure, but
 I weighed this up against the benefit of having useful backtraces for the
 duration of the release, and decided it was a risk worth taking, given
 that we usually run all the test cases on all machines once with the final
 frozen version.  However, I leave the decision to you.

 The option -rdynamic is a compiler option - see the manual entry above.
 I'm not sure why we don't use the -export-dynamic flag directly with the
 linker.  I discovered rdynamic using google over a year ago and used it,
 and it worked, both on gcc and intel.  The "on architectures that support
 it" might indicate that -export-dynamic would give an error on some
 architectures, so maybe we are using some logic in rdynamic.
