Please check if you got multiple versions of OCCT/OCE installed on your system. The cause is likely that the headers mismatch the shared libraries. Did you compile OCE by yourself?
EDIT: I got the exact same error message a while ago

EDIT: An one general tip.
If you want to search this forum or the occt changelogs for a symbol please use a tool or the webservice http://demangler.com/ to demangle the c++ symbols.

Thank you, removing all that I found of occ and freecad and rebuild both fixed the problem
