LMDBG 提供一组小工具用来收集和分析 malloc/realloc/memalign/free 函数调用的日志。LMDBG 不提供任何方式用来检测 malloc() 内存分配的超支分界。LMDBG 可检测内存泄漏和重复释放。LMDBG 可生成全堆栈日志。
- lmdbg-sym no longer segfaults due to problems with stacktrace(3).
- A much simpler and correct address conversion method was added.
- There were significant speedups due to optimizations for gdb.
- In lmdbg-run, GLIBC malloc hooks are no longer used.
- lmdbg's own code is not included in stacktraces.
- A new -N option was added, and the -v option received a minor fix.
- lmdbg-stat received fixes for a NULL dereference that appeared if a free(3) or realloc(3) stacktrace was without an appropriate malloc/realloc(3) stacktrace.
- There were other minor fixes and improvements, improvements in regression tests, and improvements in stacktrace(3)
