--- Comment #8 from Pete Moore <petemoore at gmx dot net> --- Ah, I think I see! The (output?) buffer is 32Kb, so this was happening at a 32Kb boundary, so almost any change would move this condition away from the 32Kb boundary... I'm guessing it is the output buffer that has this buffer, rather than the input, which would explain why whitespace changes didn't resolve the issue, because they wouldn't affect the output of the preprocessing stage, which itself removes whitespace. Is that about right? -- You are receiving this mail because: You are on the CC list for the bug.
