I do not think that the trouble lies within free.c... most likely, an
invalid buffer is being freed by the caller.

Did you try to run the Release mode application from within the Visual
C++ debugger? It would help a lot to have a back trace; even if it can
be somewhat crippled being compiled in release mode. You can activate
logs, add printf, whatever to try to pinpoint the problem.

We can't help you much more than this, since an Access violation can
mean anything...
