False positive assertWithSideEffect with function pointer comparison

[correctmost]

I am seeing a false positive assertWithSideEffect warning when an assert contains a function pointer comparison.

Here is sample code based on code from glib-networking:

#include <assert.h>

typedef struct
{
  bool field;
} st;

static bool handshake ()
{
  st *priv;
  priv->field = true;
  return true;
}

int main()
{
  bool (*fptr)() = handshake;
  assert (handshake == fptr);  # warning: Assert statement calls a function which may have desired side effects: 'handshake'. [assertWithSideEffect]
  return 0;
}

I don't think a function call is actually being made in this case.

Versions tested:
dfcec18902 and 2.21.1 (Arch Linux)
