Hi Alan.

I don't know if you want this or someone else, but here is the results
from gdb 

Program received signal SIGSEGV, Segmentation fault.

If there is anything else needed, please let me know.  This is instantly
recreatable.

I look forward to hearing from someone on this.


Thanks

Hi Alan.

Thanks for the procedure to find the error.

The reason we (I) didn't go with 2.18 was because there was some problem
between binutils 2.18 and GCC 4.2.  The problem was going to be fixed in
GCC 4.3.  And, GCC 4.3 at the time we started this journey was still
beta.

Any reason why you didn't go to binutils 2.18?

Build binutils with debug info, eg. make CFLAGS="-g -O -fno-inline"
then run ld under gdb to see where the problem occurs.
