Add atl_free() for cross-DLL memory management on Windows#41
Merged
Conversation
On Windows, each DLL can have its own CRT heap. Memory allocated by ATL functions like attr_list_to_string() and atl_base64_encode() must be freed by ATL, not by the calling application, to avoid heap corruption. Add atl_free() function that callers should use to free strings returned by ATL functions. Bump version to 2.3.0. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
