At first sight this is a bug in the PCRE2 library, attempting to allocate
minus 16 bytes of memory.

It also looks like a rather expensive way in the config of phrasing

header_line_maxsize = 7999
spool_wireformat = false

A_check_mime:
warn
condition = ${if > {$max_received_linelength}{7999}}
message = MIME error: Line length in message or single header
exceeds 8000.
log_message = DENY: MIME Error (Maximum line length exceeded)

on my system, pcre2 was not recently updated (last on Jan 2023) but the issue
started with exim 4.97

Thanks for the hint, it's a very old config, i fixed it.

Pcre2 was released end of 2015 whixch was more than ten years after the
indroduction of amd64. At this time 64bit was already the norm. It is
very unlikely that Pcre2 has more bugs that show up on 64bit
architectures.
