dwarf_expr: unhandled 0x12 DW_OP_ operation

I'm trying to use pfunct to identify software that bundles internal
copies of common libraries (I've started with zlib's adler32 function
for now), and I've seen this message being repeated tons of times for
kile, kxmleditor, VirtualBox and a lot more stuff.

Has anybody an idea of what that means?

Thanks,
