A few years ago, I had a similar need. I made a small library which overload malloc (and free) and display caller (using backtrace_symbols function). Next I loaded it using LD_PRELOAD. The main problems are : * it only work for malloced memory (not mmaped memory) * It is difficult to interpred efficiently information provided. Name of caller may not be sufficient to understand why memory is allocated. -- Jérôme Pouiller <[email protected]> -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
