------- Additional Comments From reichelt at gcc dot gnu dot org  2003-10-05 19:40 -------
Here's a reduced code snippet that crashes on i686-pc-linux-gnu:
when compiled with "-O":

======================================
struct A
{
    ~A();
};

inline const A foo()
{
    A a;
    return a;
}

A bar()
{
    return foo();
}
======================================

This seems to be a problem with the const qualifier.

I'm removing the target/build/host-triples since this seems
to be a generic problem.

It's a regression that was introduced in August according to Phil's
regression hunter:
: Search converges between 2003-08-20-trunk (#378) and 2003-08-21-trunk (#379).
