Dear all,

the fix for PR108527 came with a testcase that revealed a latent
bug with array sections and invalid array declarations.  The ICE
first popped up on powerpc64-linux-gnu (big endian), but the issue
was not so clear as such on x86_64-pc-linux-gnu, as it did not show
up e.g. in valgrind.  The traceback provided by Bill provided the
right hints, after which the fix became trivial and obvious.

Regtested on x86_64-pc-linux-gnu and confirmed on powerpc64-linux-gnu
by Bill in the PR.  Pushed as:

Thanks,
Harald
