LGPLv3 - is GPLv2 incompatibility transitive?

[Andreas Metzler <ametzler@bebt.de>]

Hello,

I think this is a very simple question but I somehow failed at
search^Wfinding:

We know this is in not distributable:
[GPLv2 program] linked with [LGPLv3+ library]

How about this, with indirect linkage:
[GPLv2 program] li.w. [LGPLv2+ library] li.w. [LGPLv3+ library]

One way to look at it is as a huge aggregated work including two parts
with incompatible licenses.

The other way round is to look at the two pieces on the right and say
that it is perfectly fine for a LGPLv2+ library to be linked against a
LGPLv3+ library without being upgraded to LGPLv3 [1], and therefore
the GPLv2 program can use it.

Is there a canonical interpretation?

Thanks, cu Andreas
