    return 0;

Similar to #76 but not the same.

[kervinck]

This is in fact the same type of register spilling issue as #76. We can solve it with #76, or workaround it by replacing SUBW with XORW for the relational operator (this could be part of #64).

This issue should be closed since glcc fixes it.
