Question

Can you recommend a good debugging malloc library for linux? I know there are a lot of options out there, I just need to know which libraries people are actually using to solve real-life problems.

Thanks!

EDIT: I know about Valgrind, but sometimes the performance is really too low.

Answer 1

Valgrind. :-) It's not a malloc library, but, it's really good at finding memory management and memory usage bugs.
