I'll get this together on Monday when I have access to the box.

Not sure I can wedge gdb into the kernel makefile, but I'll take a look 
at it. It doesn't give a complete backtrace, but the output lists the 
function that died. I just can't remember the name, though I seem to 
recall that it was the same function every time it crashed.

Definitely not a disk space issue. I suspect that it might be a memory 
problem, but I've got a 2GB swap partition.

This a suite of 7 programs and a set of libraries that take about 10 
minutes to compile on FC6 and F10. The kernel compile on FC6 takes about 
20 minutes.

I'll have to time it, but it dies after building about the first 
(apprxoimately) 20 modules. If I run make again, it successfully 
compiles the module that it died on, and then segfaults after compiling 
another 5 to 10 modules. Repeat make, same behavior. It eventually 
finishes the build, but the resulting kernel won't boot.

Same config file builds a working kernel using FC6 (with a much older gcc).

Thanks for your help.
