If there's anything we can do to zoom in on the problem that would help. Significant inaccuracy in trig functions probably is a bug. Having said that, Standard C does not guarantee any particular accuracy for these funtions. Also, this is probably not a bug in GCC itself but in whatever C library you're using. Andrew.
