Here's a reduced testcase that crashes mainline (with checking enabled)
on i686-pc-linux-gnu. Just compile with -Os:

==================================
void foo(char *p)
{
    __asm__ ("" ::: "memory");
}

void bar()
{
    static char *p;
    foo(p);
}
==================================

The error message is:

PR16443.c: In function `bar':
PR16443.c:7: error: Expected an SSA_NAME object
p<D1122>

#   p<D1122> = V_MAY_DEF <p<D1122>>;
__asm__("":::"memory");

PR16443.c:7: internal compiler error: tree check: expected ssa_name, have
var_decl in verify_def, at tree-ssa.c:126
Please submit a full bug report, [etc.]
