In the macOS 26 SDK, xmlFree is defined as a macro for free. This causes
issues where a same-named variable is used. Renaming the variable to
should_free resolves the issue.
See:
$ grep -B4 -A2 -n "#define xmlFree(" "Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX26.sdk/usr/include/libxml/globals.h"
261-#if defined(LIBXML_HAS_DEPRECATED_MEMORY_ALLOCATION_FUNCTIONS)
262-#define xmlMalloc(size) malloc(size)
263-#define xmlMallocAtomic(size) malloc(size)
264-#define xmlRealloc(ptr, size) realloc((ptr), (size))
265:#define xmlFree(ptr) free(ptr)
266-#define xmlMemStrdup(str) strdup(str)
267-#endif
