We need to know what is the problem, so building with debugging turned
on is needed. Also try different grades of optimization, what do you
use now, e.g. -O3? Does it work with -O2 then, and so on. There are
several bugs in the optimizer, i.e. the unit-at-a-time stuff is breaking
a lot of code, however this is not a bug, this is by design;)
If it is a problem with the optimizer we will figure out which flag
breaks the binary and report a bug.
