Subject: [Fix] Use rspamd printf format specifiers instead of GNU
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=efa297399c831744c471f28787c517c8b28c29b0;p=thirdparty%2Frspamd.git

[Fix] Use rspamd printf format specifiers instead of GNU

Fix format strings in hs_cache_backend.c and re_cache.c to use rspamd's
custom printf specifiers:
- %uz for gsize (unsigned size_t), not %z
- %ud for unsigned int, not %u

The GNU format specifiers cause crashes on some platforms.
