This more simplifed version of your last testcase also catch -O2 problem:

#include<cassert>

typedef int __attribute__((__mode__(__DI__))) off_t;

static long long min() throw() { return -9223372036854775807LL - 1; }
static long long max() throw() { return 9223372036854775807LL; }

void
seekoff(off_t __off)
{
  if (__off > max() || __off < min())
    assert(false);
}

int main() {
  seekoff(10);
  return 0;
}
