[Bug inline-asm/27301] New: ICE on convoluted inline asm with "m" (statement expression)

[jakub at gcc dot gnu dot org]

inline void
foo (void *ptr, long n)
{
  __asm__ __volatile__ ("" : : "m" (__extension__
                                    ({ struct { char x[n]; } *p = ptr;
                                     *p; })));

}

void
bar (void)
{
  char buf[16];
  foo (buf, sizeof foo);
}

ICEs in tree_cst_low, apparently GCC attempts to create a VLA through non-VLA
mechanism (expand_one_stack_var).
