Hi,

looks like a difficult crash. I do think valgrind should be our tool to find
the issue (I presume you passed --smc-check=all to valgrind). If it is really a
JIT error, and the jit code reads beyond the end of the input buffer, valgrind
must be able to catch it. Please create a small example with the pattern and
input buffer (or just copy it here if it is public). Allocate the input buffer
dynamically, so valgrind knows the start and end.

I see you use PCRE 8.35. Philip Hazel just released PCRE 8.37-RC1. You can
download it from:

ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/

Is the crash still there? Anyway, this is the right time to fix this before
releasing 8.37 :)

Regards,
Zoltan
