Re: [csmith-bugs] Assertion fail

To reproduce this bug, we need to know two things:

  + what version of Csmith you are running
  + the seed that Csmith chose that led to the crash

You should be able to get both of these from output file ("text.c").
Can you provide us with those things?

If you choose the probabilities oddly, Csmith can get into situations in which
it cannot make progress.

Currently, we prioritize these sorts of problems far below Csmith crashes.
