  It could conceivably be a problem related to long section name handlings.
Can you send a copy me the original DLL (off list)?

  Well the obvious thing is that your end-users won't be able to debug it; you
might want to leave the choice up to them, or ship both versions.  I imagine
disk/flash space on the final devices is quite limited and you might want to
strip DLLs to conserve space, but do you also work with em/simulators that
have more space where debuggable versions would be an advantage?
