Hmm, I cannot reproduce this with 4.0.0 20050215 on i686-pc-linux-gnu, so either this is new as of
yesterday or it was just a fluk. I am thinking the former.

It was the former, it regressed from the last two days, reducing.

Reduced testcase:
void f(void);
typedef __SIZE_TYPE__ size_t;
void g(void *a)
{
size_t b = (size_t)a;
switch (b)
{
case 1:
f();
break;
}
}
This looks very much related to PR 20009 as I think it was caused by the same patch.

Yeah, it is caused by that part of my patch.
The result of convert_to_integer is in one case
<nop_expr (size_t) <convert_expr (unsigned int) <param_decl (pointer) >>>
and without that part of the patch:
<nop_expr (size_t) <convert_expr (int) <param_decl (pointer) >>>
But fold folds the former into <nop_expr (size_t) <param_decl (pointer) >>
while in the latter case fold does nothing with it.
And expand_case is not prepared to deal with POINTER_TYPE's in SWITCH_COND.
Anyway, as already the other part of the PR middle-end/19857 fix is sufficient
to fix the bug, I'm leaning towards reverting the convert.c (convert_to_integer)
part of the patch and give it a shot after 4.0 branches.
