>Description:
When compiling 64-bit C++ shared libraries and programs under Solaris, GNU ld fails to do the final linking.  It is unclear whether this is a gcc or binutils bug.  I have tried gcc-3.1.1 and later branch versions, and binutils 2.12.1 and later branch versions, with same results.

The trigger when it starts failing is to have multiple "main" program object files.  With one, it works always.

In my machine, the final liking fails like:

g++ -m64 -mcpu=ultrasparc -v -o link-test main_1.o main_2.o -L`pwd` -ll_1

>How-To-Repeat:
link-test.pl will try to generate and compile couple of small shared libraries, main objects and link them in the current directory.  The script is overly parametrized to find out when it starts breaking.
