`freelist' in the library isn't a function, it's an array used by
`malloc'.  And that's exactly why the program crashes: the first time
the startup code calls `malloc' (to allocate the `environ' array),
`freelist' should be zeroed out, but it isn't!

Yes.  The current development sources already do that, so this problem
will go away when DJGPP v2.03 is released.
