Hi all,

I'm running into some memory management issues: in particular, a malloc 
error that claims I am modifying an object after freeing it: see this 
question. 
<https://groups.google.com/forum/#!searchin/julia-users/malloc/julia-users/mb5L9i7cu-E/FYt17FdAAQAJ>
 The 
error is, 

julia(9849,0x7fff705d0300) malloc: *** error for object 0x7f96a332f408: 
incorrect checksum for freed object - object was probably modified after 
being freed. *** set a breakpoint in malloc_error_break to debug

I'm not sure how to debug it: what's the best way to search for code that 
might be modifying an object after freeing it in Julia? (For example, I 
don't know what or where malloc_error_break is.)

Thanks!
Madeleine
