An out-of-bounds stack write flaw was found in unixODBC on 64-bit
architectures where the caller has 4 bytes and callee writes 8 bytes.
This issue may go unnoticed on little-endian architectures, while
big-endian architectures can be broken.

+Subject: [PATCH] PostgreSQL driver: Fix incompatible pointer-to-integer types
+
+These result in out-of-bounds stack writes on 64-bit architectures
+(caller has 4 bytes, callee writes 8 bytes), and seem to have gone
+unnoticed on little-endian architectures (although big-endian
+architectures must be broken).
+
+This change is required to avoid a build failure with GCC 14.
+
+CVE: CVE-2024-1013
