It's unlikely this is right.  This symbol is the code for the function 
GHC.Base.$s$dmin, which is a specialised version ($s) of the default method ($d) 
for min, in class Ord.  I very much doubt that min calls malloc()!

So it probably means that there are some symbols missing in your program binary. 
  Try asking gdb what lies at that address, maybe?
