[U-Boot-Users] sandpoint8245 Build fails with optimization turned off

[Eric Olsen]

I was attempting to debug an issue so I wanted to turn off the 
optimization (change from -Os to -O0 in config.mk) so I can more easily 
step thru code in gdb.  When I do this for the sandpoint8245 target I 
get the following error.  I am using u-boot 1.1.4 pulled down yesterday 
and gcc 4.0.1 toolchain built by crosstool.

Has anyone else managed to fix this?

Thanks
