Todate, I have been running mythtv binaries. Last night I tried to
compile mythtv svn and gcc crashed 3 times with segmentation faults. I
began to think overheating or bad ram. I took out the older stick of ram
and myth compiled twice cleanly. I ran memtest at work and it found
errors in the ram.
Hopefully, this was the cause of all my problems. I'll watch and see.
