>Release:        GCC 3.1 CVS from 2002-02-12
>Organization:
>Environment:
Debian GNU/Linux unstable, x86
>Description:
When the call is expanded, there does not seem to be a target tree for the returned object, although GCC cannot determine its size and thus needs one.

The problem disappears if the type conversion is removed, so the test case is probably minimal.
>How-To-Repeat:
Compile the attached code.
>Fix:
Unknown.  The bug might be caused by the incomplete merge from the ACT tree.
