Buildroot BUG

[IGOR LURI]

Building Buildroot with binutils version 2.14.90.0.8 and GCC 3.4.3, 
I can build u-boot correctly, and it works. But I can´t boot a Linux kernel 
compiled with this gcc, when Linux is booting it crashes with a segmentation fault. 
However, if I use gcc 2.95.4 and binutils 2.12.1 to build it, it boots correctly.

I want to use gcc version 3.x . What version of binutils and gcc should I use to build u-boot and Linux kernel properly?

	This is actually a bug in the u-boot linker scripts.  I haven't 
	submitted a fix, since every target has its own linker script.  I don't 
	have the fix in front of me, but here's what I remember.  If the 
	compiler has sections that aren't mentioned in the linker script, the 
	data can go between "__u_boot_cmd_start = .;" and 
	".u_boot_cmd:{*(.u_boot_cmd)}".

	Looking at u-boot.map, I noticed 2 new sections that were getting put in 
	that space.  I was using gcc 3.4.3 for PPC built with buildroot.  Anyway 
	all I had to do was to add the 2 sections above with the others.
