I'm on perl 5.22.0 and List::MoreUtils 0.413.

Dumping $envres->[2][0]{time} with Devel::Peek reveals something:

When there is no warning: 

SV = PVNV(0x279ae10) at 0x25ca100
  REFCNT = 1
  FLAGS = (POK,IsCOW,pPOK)
  IV = 0
  NV = 0.00217268600128591
  PV = 0x2895f60 "0.0022"\0
  CUR = 6
  LEN = 10
  COW_REFCNT = 3

When there is a warning: 

SV = PVNV(0x196bf40) at 0x170b110
  REFCNT = 1
  FLAGS = (POK,pPOK)
  IV = 0
  NV = 0.002889619519036

  CUR = 5
  LEN = 10

Trying this with a few other perls: doesn't happen in 5.10.1, always seems to happen in 5.18.4, never seems to happen in 5.20.3 happens too in 5.20.3.
