Still sounds like a hardware problem. Maybe the laptop is overheating,
compiling software is always hard on a system. Also I don't think
Memtest86 will show you anything even if your ram is bad. The best way
to find out is to just change it out if you have extra somewhere or
remove part of it and/or shuffle it around.

Check for thermal issues, maybe build the kernel with the laptop in
the refrigerator or something :-). If you do something like that make
sure you don't get condensation buildup when you take it out of the
cold and into the warm... but the humidity is always low in the winter
so it shouldn't be to much of a problem.
