Here is a list of issues with Boehm GC:

1) the default C++ interface does not play well with C++ (as Boehm says

2) in order to have GC'd threads, you need to replace native thread creation
calls with Boehm GC thread creation calls. This means the Boehm GC library
can not be used with third-party libraries that contain a threading API on
top of native threads.

3) if you allocate data before calling GC_INIT() (for example, when
initializing global variables), then they might not be collected. This is
platform-specific, i.e. it works with some platforms, it does not work with
some other platforms.

4) it's not clear what happens with allocations from DLLs.

This library is not better than Boehm's gc (certainly slower than Boehm's),
but it is portable C++.
