I have been seeing the message looping in map_segments from collect2. The
problem, and a possible fix, are discussed at
http://sourceware.org/ml/binutils/2006-12/msg00238.html. I downloaded and built

Hi Richard,
Please could you upload a (small) test case so that we can reproduce the
problem ? Ideally we would like to be able to include this test case in the
linker testsuite as well, in order to make sure

#include stdio.h

Sorry, my mistake.
Indeed it's the .debug_frame that is a problem (GDB uses both).

The difference between gold and GNU ld seems to be that when GNU ld sees a
comdat section with a different
