Memory leak in ucl_parser_new() / ucl_parser_register_macro() #345
Description
When using libucl’s parser with a specially crafted input (testcase: ucl_add_string_fuzzer_18191.bin), I observed a significant memory leak: many large allocations in ucl_parser_new() and related functions are not freed. The leak was detected via AddressSanitizer/LeakSanitizer.
Reproduction command and output:
