I can reproduce this on my bast, so no need to reboot your netwinder. The problem ist, that I did not implement correct rounding for the sqrt algorithm, because this involves a bit thinking to do it correctly. So, if you use FastFPE, the LSB of the result of an sqrt instruction can be wrong with a chance of 50%. For most applications this is tolerable. Nevertheless, I will correct this once I have time. Would you offer yourself as test person for the fix once it is done? If it is a program compiled by yourself, you can avoid the problem by using the -O0 optimisation switch, this lets gcc not inline the sqrt instruction, but instead call a library function which does the work by hand.
