AFAIK, David Schultz is already > looking into this, in order to have this collection of tests work again :-) Actually, it's an i386-specific gcc bug in the parsing of hexadecimal floating-point constants. I have a good idea of which change between gcc 3.3 and 3.4 broke it, but it looks like it will be difficult to get a gcc developer to investigate. This is because it only happens on platforms that have an extended precision long double format but only double precision evaluation, and FreeBSD/i386 is the only platform like that.
