題目: Re: [pcre-dev] Fix for buffer read after the end
The second one. The bugs are in new code, and released with 8.32. Release 8.31 is not affected. Now fixed in trunk. Actually JIT in 8.32 contains several new optimizations, so it is much faster than 8.31, but it seems new bugs are introduced as well.

Zoltan
