Subject Re: [firebird-support] pointer returned by FREE_IT not allocated by ib_util_malloc
The code is a bit involved because it supports multiple versions of Firebird and multiple OSes. However, the windows version calls this function to get the buffer returned by FREE_IT:

static char *
GetResultBfr (int len)

return ((char *) ib_util_malloc (len));

My DLL is linked to the ib_util.dll using an import library. So it is statically linked to the DLL but not to the underlying object files. I already checked the system in question and there are no stray copies of ib_util.dll floating around. Just the one in the Firebird installation directory.
