Bug ID: 3072
Summary: Safer coding
Product: Exim
Version: 4.97
Hardware: All
OS: All
Status: NEW
Severity: bug
Priority: medium

function_store_malloc() and function_store_get()
are given a size_t (unsigned long, 64bit on many current machines)
which is cast/truncated to int (signed 32bit on many machines).
If PCRE2 should request a large (say >4GB) amount of store and use it, things
will go bang.
Existing patch

- written for 3047 - should suffice.
