Also, I've tried running my project w/ou the optimizer library, and the Poppler code performed perfectly. So even if the optimizer is not at fault (and I think it highly likely that it is, and is causing Poppler calls to be misdirected) then the optimizer is definitely key to the problem.
EDIT: Oh yes, and I keep forgetting, at the end of my build I always see this: warning: libstdc++.so.5, needed by /usr/local/lib/libPdfOptimizeAPI.so, may conflict with libstdc++.so.6. Who knows, that could be part of the problem.
