This is a very recent regression.
It worked with 20041216 but fails with 20041223.

Reduced testcase:
struct QChar {
QChar( char c );
QChar( const QChar& c );
unsigned short ucs;
} ;
void f(QChar *uc, unsigned short ch, QChar replacement)
{
*uc++ = ((ch) ? QChar((1)) : replacement);
}

------- Additional Comments From mmitchel at gcc dot gnu dot org 2004-12-24 20:26 -------
The front end is generating as the RHS:
(INDIRECT_REF
(NOP_EXPR
(ADDR_EXPR
(TARGET_EXPR
(COND_EXPR
...)))
which seems reasonable. The LHS is:
(INDIRECT_REF
(SAVE_EXPR
(POSTINCREMENT_EXPR
(PARM_DECL))))
which also seems reasonable.
Due to my patch, we now call gimplify_cond_expr on the RHS, with the "target"
parameter non-NULL. That causes us to call gimplify_expr on the LHS, with
fb_lvalue, which aborts, because the gimplifier doesn't have a good place to put
the post-increment.
Adding a post_p parameter to gimplify_cond_expr fixes the problem (and passing
it down to gimplify_expr) fixes the problem.
Is there any reason that's not a bad idea?

Nope. The reason it doesn't have the parameter now is because it didn't use it,
and for private functions missing parameters are superior to ATTRIBUTE_UNUSED.
