Hi Klaus, 

 
no difference 

 
$ /usr/gcc/10/bin/g++ -fcommon -g -o jens -l exiv2 jens.cpp 
grzemba at oi-sr ~/Tests $ ./jens 
terminate called after throwing an instance of 'Exiv2::BasicError<char>'
 what(): No namespace info available for XMP prefix `gnome'
Abort (core dumped)
  
For completeness the stack 

 
$ mdb ./jens core
