------- Comment #5 from tgall dot foo at gmail dot com 2008-01-23 21:31 ------- so the call path involved here is from gcc/c-cppbuiltin.c builtin_define_with_hex_fp_value
which is calling real_to_decimal and its in that function we're running into problems. The string rep of the real is : 0x0.ffffffp128 aka __FLT_MAX_10_EXP__ I am able to do a real_to_hexadecimal successfully and get : 0x0.ffp+128 Inside of real_to_decimal once we get down to digit=rtd_divmod(&r, &pten) we're in obvious trouble as digit comes back with a value of: 7378697629483820646 which in hex comes out to be all 6's or a pattern of repeating nibbles of "0110". This is making my head hurt. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34720
