Compiler crash on template evaluation for generic static int

[arnetheduck]

Description

type ArrayBuf*[N: static int, T = byte] = object
  buf: array[N, T]

template maxLen(T: type): int =
  sizeof(T) * 2

type MyBuf[I] = ArrayBuf[maxLen(I)]

var v: MyBuf[int]

same as #24043, but with a template

workaround: be explicit about T

type ArrayBuf*[N: static int, T] = object
  buf: array[N, T]

template maxLen(T: type): int =
  sizeof(T) * 2

type MyBuf[I: type] = ArrayBuf[maxLen(I), byte]

var v: MyBuf[int]
