odin test console logger and fmt.printf not finishing flushing

[gco-bmx]

Context

running below via odin test does not output the complete string on the console.
I see the same behavior with the console logger,
when step debugging after io.flush(w) in wprintf in fmt.odin, I see the full string
using odin run full string is output running equivalent from main
same behavior in command prompt and powershell

@(test)
parser_basic :: proc(t: ^testing.T) {
  b := strings.builder_make()
  fmt.sbprintf(&b, "i:%v", 0)
  for i:=1; i < 4096*16; i+=1 {
    fmt.sbprintf(&b, ",i:%v", i)
  }
  fmt.printf("str:%v\n", transmute(string)b.buf[:])
  testing.expect(t, strings.builder_len(b)!=0, "there was an error")
}
