Description arno 2011-07-09 09:17:03 UTC 
Hi,
when using cairo with big double numbers (ie about 8 400 000), an overflow appears in _cairo_fixed_from_double and input is transformed to a negative value. In attached testcase, output should be:
path: 8400000.000000 0.000000 8400000.000000 200.000000
but is actually:
path: -8377216.000000 0.000000 -8377216.000000 200.000000

bug does not appear with 8300000 and below.

This is possibly related or even the same bug as #20091.
