this seems more likely to be a gcc-3.4 'bug' than an amd64 one
I can't reproduce it with gcc 3.4.3 on x86. sorry. line 164 reports: stream.setByteOrder(QDataStream::LittleEndian); I can't see a problem here.
Can you try with the latest version 0.0.20041107? Bug 73384 reports that it works on amd64, maybe this bug can be closed fixed?
I thought it was closed, the compile now works. -B
