Confirmed.
The good news is that the bug is already fixed on mainline by
Richard Kenner's patch:
http://gcc.gnu.org/ml/gcc-cvs/2004-04/msg00406.html
Does a backport make sense?

More than just that kenner's patch fixed another regression dealing with VLA types so I
should expect that kenner's patch be backported for both 3.3.4 and 3.4.1.

Postponed until GCC 3.4.2.
Kenner, would you please take the time to backport your patch to 3.4.2?

Subject: Re: [3.4 regression] ICE in loc_descriptor_from_tree (fix_trunc_expr)
That's a pretty big patch to fix a pretty pathalogical case.
I'd much prefer to just add a case for FIX_TRUNC_EXPR to
loc_descriptor_from_tree that returns 0.
That's a much safer approach for a release branch.

Kenner, thanks for the reply. Would you be willing to prepare/test a
patch that does as you suggest, then?
It's literally a two-line patch, but I'm not sure I have a testing environment
that works with the 3.4 branch. I'm away this week and will check when
I get back.
