In general, you should be careful with any C code that may keep a
reference to something.  For example -- say that you allocate pull a C
string out of a Scheme bytes object, and pass the pointer to a C
function.  As long as the call is active, no GC will happen and things
are fine -- but if the C code will keep a reference to that string and
then return, then at some point in the future, the string may have
been moved.

If you use it properly (compile through mzc), then yes.
