Comment 21 for bug 277294

the issue seems to be a freetype one, fraction_length == 10 when it crashes or the power_tens has only 10 items to power_tens[10] is out of scope

when adding some printf in the code:

printf("%li\n", power_tens[10]);
 -O0 -> 174681125
 -O1 -> 0

the gcc behaviour change but that's still a code error to have an index over the table
