Details

Undiagnosed whether this is a problem with ESC not handling -0 properly or whether Math.min(0,-0) does not handle -0 properly.

This should be -Infinity:

  es> print(Infinity/Math.min(0,-0))
  Infinity
Clearly this is a problem with Math.min, since:

es> print(Infinity/-0)
-Infinity

Math.max is just as bad:

es> print(Infinity/Math.max(-0,0))
-Infinity
Summary: Negative zero woes → Math.min and Math.max don't distinguish between -0 and 0
Summary: Math.min and Math.max don't distinguish between -0 and 0 → [builtins] Math.min and Math.max don't distinguish between -0 and 0
Component: Self-hosting compiler (ESC) → Virtual Machine
This is caused by the same reason as bug 401095.
