Hi Jörg, Thank you very much for this bug report and sorry that it took me so long to answer. I try to slowly answer every mail - but it takes time.
I commited a fix where PoDoFo tries to retrieve the filename from FT_Face, this
fixes embedding if the FT_Face object was created from a filename.
I am still investigating why the delete pMetrics call fails. I am not yet sure
what is the problem.
Best regards,
Dom
