I was just noticing that after two assumes that fasm gives an error

example:

Code:

assume eax:Point
assume eax:Point
assume eax:Point

the last assume gives you the error "Invalid Name" does anyone know
why its doing this?

Yes

and it doesn't matter if the structs are the same or not

Example:

Code:

include 'win32ax.inc'
include 'macro/masm.inc'

struct Point
  x dd ?
  y dd ?
ends
struct Square Point
  side dd ?
ends
struct Circle Point
  radius dd ?
ends

start:

assume eax:Point
assume eax:Square
assume eax:Circle ; Fails here with "Invalid Name"

.end start

is there any way to 'delete' the last assume? or anything of the like?

assume reg:none but that doesn't fix this problem. The problem seems to be that the second run destroys more than it should so the third time when it tries to destroy again something to do that is missing.
