I was not able to come to a satisfactory conclusion as to the origin of the problem, and once I found a solution, I stopped looking. I'm copying debian-gcc and debian-glibc in case they're interested. Summary for debian-{gcc,glibc}: UML built with gcc-2.95 fails to run correctly on a current unstable system with a 2.4 kernel. The symptoms are very strange; This started to happen recently; UML had been building with gcc 2.95 successfully for over 9 months now with no problems.
