It could be well worth finding though. It's most likely a reliance on uninitialized memory (the only other explanation I can think of is if something is tampering with the FPU control word). That may be mostly harmless if the algorithm converges - the sign is not well defined anyway - but we have recently fixed a couple of bugs where the occasional injection of NaN or Inf values caused real trouble. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
