Current. The working version is from September 19. September 12 and
sources showed the problem. Also, I am fairly sure that some earlier
kernels showed the problem (possibly to a lesser degree) since I remember
running a standalone memory test for a few hours at one point without
finding any hardware problems. I don't remember when that was, though,
and I haven't upgraded much lately so it could be near 1.5.
Also, I use -O3 -pipe, which should use quite a bit more memory than
standard compiles.
