binutils 2.13 on solaris 2.8 has segmentation fault in startup co de |

I'm having a problem building programs that use shared libraries on Solaris
2.8 using binutils 2.13. This problem began when I installed binutils 2.13.
Before that I had binutils 2.12, which worked fine. I tried building a test
program with gcc 2.95.2, gcc 3.0.3, and gcc 3.2. The test program dies in
the startup code with a segmentation fault. I found the following shell
script that demonstrates the problem in the gnu.utils.bug newsgroup. Does
anyone know of workaround or fix to this apparent bug?
Thank you,
Douglas Richardson.
