Since commit 757fb0e5a9a61ac8d3a67e334faeea6dc0084b3f, these Informix-compat functions return 0 without changing the output parameter. Initialize the output parameter before the test call, making that obvious. Before this, the expected test output has been depending on freed stack memory. "gcc -ftrivial-auto-var-init=pattern" revealed that. Back-patch to v13 (all supported versions). Discussion: https://postgr.es/m/20250106192748.cf.nmisch@google.com
