problem using INTERFACE_BUFFER

Greetings,

I'm experimenting with INTERFACE_BUFFER, turned on MEM_DEBUG to verify 
storage is being properly freed up, and have run into a snag.

I'm using a line_t struct, adding the email to it using line_inject(), 
printing the message (usign eps_next_header(), eps_next_line(), 
mime_next_header(), mime_next_line()), and at the end calling line_kill to 
free the line_t struct.  The setup and printing work fine, but the cleanup 
at the end gives message:

	"MEM_DEBUG: MFREE: Unknown allocation space at 0x804e5d8 (Searched 1 records)"

Looking at the code, I see line_inject() uses realloc() to increase text 
storage allocation and line_kill uses mfree().  The mixture of storage 
allocation styles (libc and user) seems to be at issue.

I've taken a look at mrealloc() which would seem to be the logical answer, 
but it doesn't seem complete.

I'm using eps-1.2.  Are there any patches for it?  Is there a newer version 
available?

Thanks.

David
