Overloaded enum with {.pure.} causes nim check to segfault

[auxym]

Description

Running nim check on the following code causes a segfault:

type AC_WINCTRL_Fields* = distinct uint8

type AC_STATUSA_WSTATE0* {.pure.} = enum
  ABOVE = 0x0,
  INSIDE = 0x1,
  BELOW = 0x2,

type AC_WINCTRL_WINTSEL0* {.pure.} = enum
  ABOVE = 0x0,
  INSIDE = 0x1,
  BELOW = 0x2,
  OUTSIDE = 0x3,

proc write*(WINTSEL0: AC_WINCTRL_WINTSEL0 = ABOVE) =
  discard

I'm aware using pure with overloading is pointless, I forgot to remove the pragma as I was converting from pure enums to overloaded, which are much nicer to use. In any case, I don't believe nim should segfault.

### Expected Output

```text
No segfault :)

Possible Solution

No idea, sorry.

Additional Information

Unrelated, but if we add , typ to the semExprWithType call here the ambiguous identifier error shouldn't happen:

Awesome to see this resolved so quickly, thanks @metagn @Araq
