[Bug c/32122] New: invalid indirect goto accepted

[sabre at nondot dot org]

GCC accepts this:

void foo() { goto *1; }

The "Labels as Values" section of the doc states that indirect gotos take "Any
expression of type void *".  1 is not of type void*.

it looks like gcc accepts anything convertible to a pointer type.  Trying to
jump to a structure yields:
t.c:15: error: cannot convert to a pointer type
