Miscompilation can do about anything. There have been a number of other reports about compiler issues lately. Ingo Molnar here: http://kerneltrap.org/Linux/Compiler_Optimization_Bugs_and_World_Domination Me here: http://marc.info/?l=linux-kernel&m=119127234804440&w=2 The trend I am seeing is that we are optimizing for, and testing with, recent compilers (gcc 4.1 and later) and that older compilers tend to break, even though compilers as old as gcc 3.2 are still supposed to be supported.
