Your computer was trying to execute instructions at 0x400000.  This
smells very much like a single bit flip; ie there was a function
pointer which should have been NULL, but actually had one bit flip
and so the CPU jumped to somewhere that doesn't have any memory
backing it.

Can you run memtest86, or whatever the current flavour of memory testing
software is?
