Test numeric fails if PostgreSQL built with ASAN

[saygoodbyye]

I have used this branches:

PostgreSQL - REL_15_STABLE
pg_filedump - master

Server configuration:

PGPREFIX=/tmp/pgsql

CPPFLAGS="-Og -fsanitize=address -fsanitize=undefined -fno-sanitize-recover=all -fno-sanitize=nonnull-attribute -fstack-protector" \
LDFLAGS='-fsanitize=address -fsanitize=undefined -static-libasan' \
./configure --enable-tap-tests --enable-debug --enable-cassert --with-libxml --quiet --prefix="$PGPREFIX"

Perform installcheck:

ASAN_OPTIONS=detect_leaks=0:abort_on_error=1:disable_coredump=0:strict_string_checks=1:check_initialization_order=1:strict_init_order=1:detect_odr_violation=0 make -s installcheck

The differences that caused some tests to fail can be viewed in the
file "/home/test/work/subtree/pg_filedump/regression.diffs".  A copy of the test summary that you see
above is saved in the file "/home/test/work/subtree/pg_filedump/regression.out".
