Write a memory leak analysis in {{tone}} tone for {{target_audience}}, focusing on {{code_language}} code and using {{profiling_tool}} for profiling. Follow a systematic root cause analysis: isolate the leak, identify root cause, propose a fix, and verify. Output each leak with type, pattern (allocation point, retention cause, growth rate), and solution (code fixes, resource management, verification steps). Keep under 500 words. Every recommendation must be specific to {{code_language}} and the provided code context. Skip any section if information is unknown. Paste any relevant background information after these instructions before running.
