This series is a candidate reroll for cb/pcre2-chartables-leakfix, that hopefully addresses the root cause of the problem reported by Dscho in Windows, where the PCRE2 library wasn't aware of the custom allocator and was returning a pointer created with the system malloc but passing it to NED's free, resulting in a segfault. The reason why it was triggered by the original leak fix is the layering violation reported by René and that is exclusive to PCRE2 (hence why it hasn't been reported with PCRE1). The first patch could be droped and then used in a different series that will fully integrate the custom allocator with the PCRE library and that is currently missing with PCRE2. Eitherway, since I am unable to replicate the original bug or take performance numbers in a representative environment without Windows this is only published as an RFC, eventhough it has been tested and considered mostly complete. Junio, could you comment in my assumption that the use of grep in revision.c doesn't require initializing a PCRE2 global context and therefore not doing the cleanup?
