Thanks. The machine has shown mild signs of flakiness in the past when called
upon for CPU-intensive tasks (say compiling gcc) -- random segfaults that would
go away if I let it cool down a bit. Now it glitches on compiling gimp or some
qt libraries. Mind you, it has been a hot summer, and the ambient temperature
in the room in which it is located is about 26C. But lm-sensors doesn't show
an abnormally high core temperature.

I'll try to cool it down to see whether that matters, but it sounds like it's
time to think about getting a more reliable (and well-cooled) computer. Time
to post a general query.

Thanks for the help!
