Mine, it is STRING_CST which is causing the ICE.

Reduced testcase:
void zconfdump(void)
{
char *p, *p2;
for (p2 = p; p2; )
{
char __a0, __a1, __a2;
__a0 = ((__const char *) (\\\))[0];
if (__a0)
return;
}
}

The two if (tree_code(genop) == VALUE_HANDLE) at lines 2190 of tree-ssa-pre.c
look suspicious to me.
They aren't suspicious at all.

And here is a testcase without a simplifing opportunity:
void zconfdump(__SIZE_TYPE__ i)
{
for (;;)
{
char __a0;
__a0 = (\\\)[i];
if (__a0)
return;
}
}
