This also happens when dereferencing void pointers (this is invalid code
though, but I get the same error with the code in the first post):

void foo (void *p)
{
        asm("" :: "g" (*p));
}

$ gcc -c foo.c
foo.c: In function ‘foo’:
foo.c:3: warning: dereferencing ‘void *’ pointer
foo.c:3: internal compiler error: in gimplify_expr, at gimplify.c:6288
Please submit a full bug report,

Turns out this is not really a regression.  If you change g to r, it fails from 2.95.3 and up.
