I suspect you've found mozilla's bug. ARM doubles are mixed endian. IIRC the bits in the 32 bit words are stored little endian as you would expect, but the words are ordered big endian in memory. (At least for the ABI that Debian uses) (I will be corrected if I have this the wrong way round) Also IIRC this is perfectly legal IEEE, just mighty odd. Nicholas Clark
