[Valgrind-users] Running massif on code with custom allocator with non-malloc-like API

[Konstantin T. <an...@ya...>]

Hi all,

I'm trying to use massif to analyze memory usage of WebKit. I build it without embedded tcmalloc, so "normal" heap allocations are traced by massif. However, its JavaScript engine still uses separate mmap-based heap. How can I trace allocations made in this heap with massif? API is not malloc-like, so I guess I need to write some code to get this functions replaced in Valgrind.

P.S. I've tried --pages-as-heap=yes to trace mmap directly, but results were completely garbage.
