http://www.valgrind.org/docs/manual/mc-manual.html#mc-manual.mempools
describes what Valgrind provides for "real" custom allocators.

Now, if libast provides a set of malloc/free/... compatible functions,
then you should rather modify Valgrind to intercept these replacement.
See bug  https://bugs.kde.org/show_bug.cgi?id=219156
for a patch implementing replacements for tcmalloc library.
