Add support for ENABLE_OVERRIDE #5

Open repi opened 5 years ago

repi commented 5 years ago

To enable rpmalloc's overriding of C malloc/free functions, this enables rpmalloc to be used instead of the system allocator for C/C++ code dependencies as well, not just for Rust code.

Easy to enable (and should be a feature flag on the crates) but do have to make sure it links properly on all platforms and targets.

One caveat is that symbol replacing on Windows platforms is a proper pain and not currently implemented in rpmalloc (code for it can be found in the tcmalloc container project, gperftools, but it's quite nasty).

Thanks for the heads up! Could see that being messy
