This is bcause peel_address does not handle some trees generated by Ada (I
think it was VIEW_CONVERT_EXPR, but I may be wrong). Honza was working on it,
but then he preferred to wait for Zdenek to be back. Bootstrapping
with -fno-ivopts should be a workaround for now.

This is PR 17345. It was broken by Uros i387 patch, and Honza has a proposed
solution. See the audit trail for more infos. You may want to double-check that
the attacched patch does indeed cure the Ada failure as well.
